//	Implementation Summary
//
//	1. Enforce API surface and semantic compatibility with 1.9.x branch
//	2. Improve the module's maintainability by reducing the storage
//		paths to a single mechanism.
//	3. Use the same single mechanism to support "private" and "user" data.
//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
//	5. Avoid exposing implementation details on user objects (eg. expando properties)
//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

  /**
    An instance of `Ember.Application` is the starting point for every Ember
    application. It helps to instantiate, initialize and coordinate the many
    objects that make up your app.
  
    Each Ember app has one and only one `Ember.Application` object. In fact, the
    very first thing you should do in your application is create the instance:
  
    ```javascript
    window.App = Ember.Application.create();
    ```
  
    Typically, the application object is the only global variable. All other
    classes in your app should be properties on the `Ember.Application` instance,
    which highlights its first role: a global namespace.
  
    For example, if you define a view class, it might look like this:
  
    ```javascript
    App.MyView = Ember.View.extend();
    ```
  
    By default, calling `Ember.Application.create()` will automatically initialize
    your application by calling the `Ember.Application.initialize()` method. If
    you need to delay initialization, you can call your app's `deferReadiness()`
    method. When you are ready for your app to be initialized, call its
    `advanceReadiness()` method.
  
    You can define a `ready` method on the `Ember.Application` instance, which
    will be run by Ember when the application is initialized.
  
    Because `Ember.Application` inherits from `Ember.Namespace`, any classes
    you create will have useful string representations when calling `toString()`.
    See the `Ember.Namespace` documentation for more information.
  
    While you can think of your `Ember.Application` as a container that holds the
    other classes in your application, there are several other responsibilities
    going on under-the-hood that you may want to understand.
  
    ### Event Delegation
  
    Ember uses a technique called _event delegation_. This allows the framework
    to set up a global, shared event listener instead of requiring each view to
    do it manually. For example, instead of each view registering its own
    `mousedown` listener on its associated element, Ember sets up a `mousedown`
    listener on the `body`.
  
    If a `mousedown` event occurs, Ember will look at the target of the event and
    start walking up the DOM node tree, finding corresponding views and invoking
    their `mouseDown` method as it goes.
  
    `Ember.Application` has a number of default events that it listens for, as
    well as a mapping from lowercase events to camel-cased view method names. For
    example, the `keypress` event causes the `keyPress` method on the view to be
    called, the `dblclick` event causes `doubleClick` to be called, and so on.
  
    If there is a bubbling browser event that Ember does not listen for by
    default, you can specify custom events and their corresponding view method
    names by setting the application's `customEvents` property:
  
    ```javascript
    let App = Ember.Application.create({
      customEvents: {
        // add support for the paste event
        paste: 'paste'
      }
    });
    ```
  
    To prevent Ember from setting up a listener for a default event,
    specify the event name with a `null` value in the `customEvents`
    property:
  
    ```javascript
    let App = Ember.Application.create({
      customEvents: {
        // prevent listeners for mouseenter/mouseleave events
        mouseenter: null,
        mouseleave: null
      }
    });
    ```
  
    By default, the application sets up these event listeners on the document
    body. However, in cases where you are embedding an Ember application inside
    an existing page, you may want it to set up the listeners on an element
    inside the body.
  
    For example, if only events inside a DOM element with the ID of `ember-app`
    should be delegated, set your application's `rootElement` property:
  
    ```javascript
    let App = Ember.Application.create({
      rootElement: '#ember-app'
    });
    ```
  
    The `rootElement` can be either a DOM element or a jQuery-compatible selector
    string. Note that *views appended to the DOM outside the root element will
    not receive events.* If you specify a custom root element, make sure you only
    append views inside it!
  
    To learn more about the events Ember components use, see
    [components/handling-events](https://guides.emberjs.com/v2.6.0/components/handling-events/#toc_event-names).
  
    ### Initializers
  
    Libraries on top of Ember can add initializers, like so:
  
    ```javascript
    Ember.Application.initializer({
      name: 'api-adapter',
  
      initialize: function(application) {
        application.register('api-adapter:main', ApiAdapter);
      }
    });
    ```
  
    Initializers provide an opportunity to access the internal registry, which
    organizes the different components of an Ember application. Additionally
    they provide a chance to access the instantiated application. Beyond
    being used for libraries, initializers are also a great way to organize
    dependency injection or setup in your own application.
  
    ### Routing
  
    In addition to creating your application's router, `Ember.Application` is
    also responsible for telling the router when to start routing. Transitions
    between routes can be logged with the `LOG_TRANSITIONS` flag, and more
    detailed intra-transition logging can be logged with
    the `LOG_TRANSITIONS_INTERNAL` flag:
  
    ```javascript
    let App = Ember.Application.create({
      LOG_TRANSITIONS: true, // basic logging of successful transitions
      LOG_TRANSITIONS_INTERNAL: true // detailed logging of all routing steps
    });
    ```
  
    By default, the router will begin trying to translate the current URL into
    application state once the browser emits the `DOMContentReady` event. If you
    need to defer routing, you can call the application's `deferReadiness()`
    method. Once routing can begin, call the `advanceReadiness()` method.
  
    If there is any setup required before routing begins, you can implement a
    `ready()` method on your app that will be invoked immediately before routing
    begins.

      application's `rootElement` property.

      for a set of standard DOM events, such as `mousedown` and
      `keyup`, and delegates them to your application's `Ember.View`
      instances.
       If you would like additional bubbling events to be delegated to your
      views, set your `Ember.Application`'s `customEvents` property
      to a hash containing the DOM event name as the key and the
      corresponding view method name as the value. Setting an event to
      a value of `null` will prevent a default event listener from being

       Unfortunately, we cannot actually write this because we need to participate
      in the "synchronous" boot process. While the code above would work fine on
      the initial boot (i.e. DOM ready), when `App.reset()` is called, we need to
      boot a new instance synchronously (see the documentation on `_bootSync()`
      for details).
       Because of this restriction, the actual logic of this method is located
      inside `didBecomeReady()`.

      @method domReady

      // Continues to `didBecomeReady`
    },

    /**
      Use this to defer readiness until some condition is true.
       Example:

      let App = Ember.Application.create();

      resolves with the instance when the initial routing and rendering is
      complete, or rejects with any error that occured during the boot process.
       When `autoboot` is disabled, calling `visit` would first cause the
      application to boot, which runs the application initializers.
       This method also takes a hash of boot-time configuration options for
      customizing the instance's behavior. See the documentation on
      `Ember.ApplicationInstance.BootOptions` for details.
       `Ember.ApplicationInstance.BootOptions` is an interface class that exists
      purely to document the available options; you do not need to construct it
      manually. Simply pass a regular JavaScript object containing of the
      desired options:
       ```javascript
      MyApp.visit("/", { location: "none", rootElement: "#container" });
      ```
       ### Supported Scenarios
       While the `BootOptions` class exposes a large number of knobs, not all
      combinations of them are valid; certain incompatible combinations might
      result in unexpected behavior.
       For example, booting the instance in the full browser environment
      while specifying a foriegn `document` object (e.g. `{ isBrowser: true,
      document: iframe.contentDocument }`) does not work correctly today,
      largely due to Ember's jQuery dependency.
       Currently, there are three officially supported scenarios/configurations.
      Usages outside of these scenarios are not guaranteed to work, but please
      feel free to file bug reports documenting your experience and any issues
      you encountered to help expand support.
       #### Browser Applications (Manual Boot)
       The setup is largely similar to how Ember works out-of-the-box. Normally,
      Ember will boot a default instance for your Application on "DOM ready".
      However, you can customize this behavior by disabling `autoboot`.
       For example, this allows you to render a miniture demo of your application
      into a specific area on your marketing website:
       ```javascript
      import MyApp from 'my-app';
       $(function() {
        let App = MyApp.create({ autoboot: false });
         let options = {
          // Override the router's location adapter to prevent it from updating
          // the URL in the address bar
          location: 'none',
           // Override the default `rootElement` on the app to render into a
          // specific `div` on the page
          rootElement: '#demo'
        };
         // Start the app at the special demo URL
        App.visit('/demo', options);
      });
      ````
       Or perhaps you might want to boot two instances of your app on the same
      page for a split-screen multiplayer experience:
       ```javascript
      import MyApp from 'my-app';
       $(function() {
        let App = MyApp.create({ autoboot: false });
         let sessionId = MyApp.generateSessionID();
         let player1 = App.visit(`/matches/join?name=Player+1&session=${sessionId}`, { rootElement: '#left', location: 'none' });
        let player2 = App.visit(`/matches/join?name=Player+2&session=${sessionId}`, { rootElement: '#right', location: 'none' });
         Promise.all([player1, player2]).then(() => {
          // Both apps have completed the initial render
          $('#loading').fadeOut();
        });
      });
      ```
       Do note that each app instance maintains their own registry/container, so
      they will run in complete isolation by default.
       #### Server-Side Rendering (also known as FastBoot)
       This setup allows you to run your Ember app in a server environment using
      Node.js and render its content into static HTML for SEO purposes.
       ```javascript
      const HTMLSerializer = new SimpleDOM.HTMLSerializer(SimpleDOM.voidMap);
       function renderURL(url) {
        let dom = new SimpleDOM.Document();
        let rootElement = dom.body;
        let options = { isBrowser: false, document: dom, rootElement: rootElement };
         return MyApp.visit(options).then(instance => {
          try {
            return HTMLSerializer.serialize(rootElement.firstChild);
          } finally {
            instance.destroy();
          }
        });
      }
      ```
       In this scenario, because Ember does not have access to a global `document`
      object in the Node.js environment, you must provide one explicitly. In practice,
      in the non-browser environment, the stand-in `document` object only need to
      implement a limited subset of the full DOM API. The `SimpleDOM` library is known
      to work.
       Since there is no access to jQuery in the non-browser environment, you must also
      specify a DOM `Element` object in the same `document` for the `rootElement` option
      (as opposed to a selector string like `"body"`).
       See the documentation on the `isBrowser`, `document` and `rootElement` properties
      on `Ember.ApplicationInstance.BootOptions` for details.
       #### Server-Side Resource Discovery
       This setup allows you to run the routing layer of your Ember app in a server
      environment using Node.js and completely disable rendering. This allows you
      to simulate and discover the resources (i.e. AJAX requests) needed to fufill
      a given request and eagerly "push" these resources to the client.
       ```app/initializers/network-service.js
      import BrowserNetworkService from 'app/services/network/browser';
      import NodeNetworkService from 'app/services/network/node';
       // Inject a (hypothetical) service for abstracting all AJAX calls and use
      // the appropiate implementaion on the client/server. This also allows the
      // server to log all the AJAX calls made during a particular request and use
      // that for resource-discovery purpose.
       export function initialize(application) {
        if (window) { // browser
          application.register('service:network', BrowserNetworkService);
        } else { // node
          application.register('service:network', NodeNetworkService);
        }
         application.inject('route', 'network', 'service:network');
      };
       export default {
        name: 'network-service',
        initialize: initialize
      };
      ```
       ```app/routes/post.js
      import Ember from 'ember';
       // An example of how the (hypothetical) service is used in routes.
       export default Ember.Route.extend({
        model(params) {
          return this.network.fetch(`/api/posts/${params.post_id}.json`);
        },
         afterModel(post) {
          if (post.isExternalContent) {
            return this.network.fetch(`/api/external/?url=${post.externalURL}`);
          } else {
            return post;
          }
        }
      });
      ```
       ```javascript
      // Finally, put all the pieces together
       function discoverResourcesFor(url) {
        return MyApp.visit(url, { isBrowser: false, shouldRender: false }).then(instance => {
          let networkService = instance.lookup('service:network');
          return networkService.requests; // => { "/api/posts/123.json": "..." }

      The goal of initializers should be to register dependencies and injections.
      This phase runs once. Because these initializers may load code, they are
      allowed to defer application readiness and advance it. If you need to access
      the container or store you should use an InstanceInitializer that will be run
      after all initializers and therefore after all code is loaded and the app is
      ready.
       Initializer receives an object which has the following attributes:
      `name`, `before`, `after`, `initialize`. The only required attribute is
      `initialize`, all others are optional.
       * `name` allows you to specify under which name the initializer is registered.
      This must be a unique name, as trying to register two initializers with the
      same name will result in an error.
       ```javascript
      Ember.Application.initializer({
        name: 'namedInitializer',
         initialize: function(application) {
          Ember.debug('Running namedInitializer!');
        }
      });
      ```
       * `before` and `after` are used to ensure that this initializer is ran prior
      or after the one identified by the value. This value can be a single string
      or an array of strings, referencing the `name` of other initializers.
       An example of ordering initializers, we create an initializer named `first`:
       ```javascript
      Ember.Application.initializer({
        name: 'first',
         initialize: function(application) {
          Ember.debug('First initializer!');
        }
      });
       // DEBUG: First initializer!
      ```
       We add another initializer named `second`, specifying that it should run
      after the initializer named `first`:
       ```javascript
      Ember.Application.initializer({
        name: 'second',
        after: 'first',
         initialize: function(application) {
          Ember.debug('Second initializer!');
        }
      });
       // DEBUG: First initializer!
      // DEBUG: Second initializer!
      ```
       Afterwards we add a further initializer named `pre`, this time specifying
      that it should run before the initializer named `first`:
       ```javascript
      Ember.Application.initializer({
        name: 'pre',
        before: 'first',
         initialize: function(application) {
          Ember.debug('Pre initializer!');
        }
      });
       // DEBUG: Pre initializer!
      // DEBUG: First initializer!
      // DEBUG: Second initializer!
      ```
       Finally we add an initializer named `post`, specifying it should run after
      both the `first` and the `second` initializers:
       ```javascript
      Ember.Application.initializer({
        name: 'post',
        after: ['first', 'second'],
         initialize: function(application) {
          Ember.debug('Post initializer!');
        }
      });
       // DEBUG: Pre initializer!
      // DEBUG: First initializer!
      // DEBUG: Second initializer!
      // DEBUG: Post initializer!
      ```
       * `initialize` is a callback function that receives one argument,
        `application`, on which you can operate.
       Example of using `application` to register an adapter:
       ```javascript
      Ember.Application.initializer({
        name: 'api-adapter',
         initialize: function(application) {
          application.register('api-adapter:main', ApiAdapter);
        }
      });
      ```

       * See Ember.Application.initializer for discussion on the usage of before
      and after.
       Example instanceInitializer to preload data into the store.
       ```javascript
      Ember.Application.initializer({
        name: 'preload-data',
         initialize: function(application) {

  /**
    The DefaultResolver defines the default lookup rules to resolve
    container lookups before consulting the container for registered
    items:
  
    * templates are looked up on `Ember.TEMPLATES`
    * other names are looked up on the application after converting
      the name. For example, `controller:post` looks up
      `App.PostController` by default.
    * there are some nuances (see examples below)
  
    ### How Resolving Works
  
    The container calls this object's `resolve` method with the
    `fullName` argument.
  
    It first parses the fullName into an object using `parseName`.
  
    Then it checks for the presence of a type-specific instance
    method of the form `resolve[Type]` and calls it if it exists.
    For example if it was resolving 'template:post', it would call
    the `resolveTemplate` method.
  
    Its last resort is to call the `resolveOther` method.
  
    The methods of this object are designed to be easy to override
    in a subclass. For example, you could enhance how a template
    is resolved like so:
  
    ```javascript
    App = Ember.Application.create({
      Resolver: Ember.DefaultResolver.extend({
        resolveTemplate: function(parsedName) {
          let resolvedTemplate = this._super(parsedName);
          if (resolvedTemplate) { return resolvedTemplate; }
          return Ember.TEMPLATES['not_found'];
        }
      })
    });
    ```
  
    Some examples of how names are resolved:
  
    ```
    'template:post'           //=> Ember.TEMPLATES['post']
    'template:posts/byline'   //=> Ember.TEMPLATES['posts/byline']
    'template:posts.byline'   //=> Ember.TEMPLATES['posts/byline']
    'template:blogPost'       //=> Ember.TEMPLATES['blogPost']
                              //   OR
                              //   Ember.TEMPLATES['blog_post']
    'controller:post'         //=> App.PostController
    'controller:posts.index'  //=> App.PostsIndexController
    'controller:blog/post'    //=> Blog.PostController
    'controller:basic'        //=> Ember.Controller
    'route:post'              //=> App.PostRoute
    'route:posts.index'       //=> App.PostsIndexRoute
    'route:blog/post'         //=> Blog.PostRoute
    'route:basic'             //=> Ember.Route
    'view:post'               //=> App.PostView
    'view:posts.index'        //=> App.PostsIndexView
    'view:blog/post'          //=> Blog.PostView
    'view:basic'              //=> Ember.View
    'foo:post'                //=> App.PostFoo
    'model:post'              //=> App.Post

  /**
    Allows for runtime registration of handler functions that override the default deprecation behavior.
    Deprecations are invoked by calls to [Ember.deprecate](http://emberjs.com/api/classes/Ember.html#method_deprecate).
    The following example demonstrates its usage by registering a handler that throws an error if the
    message contains the word "should", otherwise defers to the default handler.
  
    ```javascript
    Ember.Debug.registerDeprecationHandler((message, options, next) => {
      if (message.indexOf('should') !== -1) {
        throw new Error(`Deprecation message with should: ${message}`);
      } else {
        // defer to whatever handler was registered before this one
        next(message, options);
      }
    });
    ```
  
    The handler function takes the following arguments:
  
    <ul>
      <li> <code>message</code> - The message received from the deprecation call.</li>
      <li> <code>options</code> - An object passed in with the deprecation call containing additional information including:</li>
        <ul>
          <li> <code>id</code> - An id of the deprecation in the form of <code>package-name.specific-deprecation</code>.</li>
          <li> <code>until</code> - The Ember version number the feature and deprecation will be removed in.</li>
        </ul>
      <li> <code>next</code> - A function that calls into the previously registered handler.</li>
    </ul>

  /**
    An `Ember.Component` is a view that is completely
    isolated. Properties accessed in its templates go
    to the view object and actions are targeted at
    the view object. There is no access to the
    surrounding context or outer controller; all
    contextual information must be passed in.
  
    The easiest way to create an `Ember.Component` is via
    a template. If you name a template
    `app/components/my-foo.hbs`, you will be able to use
    `{{my-foo}}` in other templates, which will make
    an instance of the isolated component.
  
    ```app/components/my-foo.hbs
    {{person-profile person=currentUser}}
    ```
  
    ```app/components/person-profile.hbs
    <h1>{{person.title}}</h1>
    <img src={{person.avatar}}>
    <p class='signature'>{{person.signature}}</p>
    ```
  
    You can use `yield` inside a template to
    include the **contents** of any block attached to
    the component. The block will be executed in the
    context of the surrounding context or outer controller:
  
    ```handlebars
    {{#person-profile person=currentUser}}
      <p>Admin mode</p>
      {{! Executed in the controller's context. }}
    {{/person-profile}}
    ```
  
    ```app/components/person-profile.hbs
    <h1>{{person.title}}</h1>
    {{! Executed in the component's context. }}
    {{yield}} {{! block contents }}
    ```
  
    If you want to customize the component, in order to
    handle events or actions, you implement a subclass
    of `Ember.Component` named after the name of the
    component.
  
    For example, you could implement the action
    `hello` for the `person-profile` component:
  
    ```app/components/person-profile.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      actions: {
        hello(name) {
          console.log("Hello", name);
        }
      }
    });
    ```
  
    And then use it in the component's template:
  
    ```app/templates/components/person-profile.hbs
    <h1>{{person.title}}</h1>
    {{yield}} <!-- block contents -->
    <button {{action 'hello' person.name}}>
      Say Hello to {{person.name}}
    </button>
    ```
  
    Components must have a `-` in their name to avoid
    conflicts with built-in controls that wrap HTML
    elements. This is consistent with the same
    requirement in web components.
  
  
    ## HTML Tag
  
    The default HTML tag name used for a component's DOM representation is `div`.
    This can be customized by setting the `tagName` property.
    The following component class:
  
    ```app/components/emphasized-paragraph.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      tagName: 'em'
    });
    ```
  
    Would result in instances with the following HTML:
  
    ```html
    <em id="ember1" class="ember-view"></em>
    ```
  
  
    ## HTML `class` Attribute
  
    The HTML `class` attribute of a component's tag can be set by providing a
    `classNames` property that is set to an array of strings:
  
    ```app/components/my-widget.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      classNames: ['my-class', 'my-other-class']
    });
    ```
  
    Will result in component instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view my-class my-other-class"></div>
    ```
  
    `class` attribute values can also be set by providing a `classNameBindings`
    property set to an array of properties names for the component. The return value
    of these properties will be added as part of the value for the components's `class`
    attribute. These properties can be computed properties:
  
    ```app/components/my-widget.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      classNameBindings: ['propertyA', 'propertyB'],
      propertyA: 'from-a',
      propertyB: Ember.computed(function() {
        if (someLogic) { return 'from-b'; }
      })
    });
    ```
  
    Will result in component instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view from-a from-b"></div>
    ```
  
    If the value of a class name binding returns a boolean the property name
    itself will be used as the class name if the property is true.
    The class name will not be added if the value is `false` or `undefined`.
  
    ```app/components/my-widget.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      classNameBindings: ['hovered'],
      hovered: true
    });
    ```
  
    Will result in component instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view hovered"></div>
    ```
  
    When using boolean class name bindings you can supply a string value other
    than the property name for use as the `class` HTML attribute by appending the
    preferred value after a ":" character when defining the binding:
  
    ```app/components/my-widget.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      classNameBindings: ['awesome:so-very-cool'],
      awesome: true
    });
    ```
  
    Will result in component instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view so-very-cool"></div>
    ```
  
    Boolean value class name bindings whose property names are in a
    camelCase-style format will be converted to a dasherized format:
  
    ```app/components/my-widget.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      classNameBindings: ['isUrgent'],
      isUrgent: true
    });
    ```
  
    Will result in component instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view is-urgent"></div>
    ```
  
    Class name bindings can also refer to object values that are found by
    traversing a path relative to the component itself:
  
    ```app/components/my-widget.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      classNameBindings: ['messages.empty'],
      messages: Ember.Object.create({
        empty: true
      })
    });
    ```
  
    Will result in component instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view empty"></div>
    ```
  
    If you want to add a class name for a property which evaluates to true and
    and a different class name if it evaluates to false, you can pass a binding
    like this:
  
    ```app/components/my-widget.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      classNameBindings: ['isEnabled:enabled:disabled'],
      isEnabled: true
    });
    ```
  
    Will result in component instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view enabled"></div>
    ```
  
    When isEnabled is `false`, the resulting HTML representation looks like
    this:
  
    ```html
    <div id="ember1" class="ember-view disabled"></div>
    ```
  
    This syntax offers the convenience to add a class if a property is `false`:
  
    ```app/components/my-widget.js
    import Ember from 'ember';
  
    // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false
    export default Ember.Component.extend({
      classNameBindings: ['isEnabled::disabled'],
      isEnabled: true
    });
    ```
  
    Will result in component instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view"></div>
    ```
  
    When the `isEnabled` property on the component is set to `false`, it will result
    in component instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view disabled"></div>
    ```
  
    Updates to the value of a class name binding will result in automatic
    update of the  HTML `class` attribute in the component's rendered HTML
    representation. If the value becomes `false` or `undefined` the class name
    will be removed.
    Both `classNames` and `classNameBindings` are concatenated properties. See
    [Ember.Object](/api/classes/Ember.Object.html) documentation for more
    information about concatenated properties.
  
  
    ## HTML Attributes
  
    The HTML attribute section of a component's tag can be set by providing an
    `attributeBindings` property set to an array of property names on the component.
    The return value of these properties will be used as the value of the component's
    HTML associated attribute:
  
    ```app/components/my-anchor.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      tagName: 'a',
      attributeBindings: ['href'],
      href: 'http://google.com'
    });
    ```
  
    Will result in component instances with an HTML representation of:
  
    ```html
    <a id="ember1" class="ember-view" href="http://google.com"></a>
    ```
  
    One property can be mapped on to another by placing a ":" between
    the source property and the destination property:
  
    ```app/components/my-anchor.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      tagName: 'a',
      attributeBindings: ['url:href'],
      url: 'http://google.com'
    });
    ```
  
    Will result in component instances with an HTML representation of:
  
    ```html
    <a id="ember1" class="ember-view" href="http://google.com"></a>
    ```
  
    Namespaced attributes (e.g. `xlink:href`) are supported, but have to be
    mapped, since `:` is not a valid character for properties in Javascript:
  
    ```app/components/my-use.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      tagName: 'use',
      attributeBindings: ['xlinkHref:xlink:href'],
      xlinkHref: '#triangle'
    });
    ```
  
    Will result in component instances with an HTML representation of:
  
    ```html
    <use xlink:href="#triangle"></use>
    ```
  
    If the return value of an `attributeBindings` monitored property is a boolean
    the attribute will be present or absent depending on the value:
  
    ```app/components/my-text-input.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      tagName: 'input',
      attributeBindings: ['disabled'],
      disabled: false
    });
    ```
  
    Will result in a component instance with an HTML representation of:
  
    ```html
    <input id="ember1" class="ember-view" />
    ```
  
    `attributeBindings` can refer to computed properties:
  
    ```app/components/my-text-input.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      tagName: 'input',
      attributeBindings: ['disabled'],
      disabled: Ember.computed(function() {
        if (someLogic) {
          return true;
        } else {
          return false;
        }
      })
    });
    ```
  
    To prevent setting an attribute altogether, use `null` or `undefined` as the
    return value of the `attributeBindings` monitored property:
  
    ```app/components/my-text-input.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      tagName: 'form',
      attributeBindings: ['novalidate'],
      novalidate: null
    });
    ```
  
    Updates to the property of an attribute binding will result in automatic
    update of the  HTML attribute in the component's rendered HTML representation.
    `attributeBindings` is a concatenated property. See [Ember.Object](/api/classes/Ember.Object.html)
    documentation for more information about concatenated properties.
  
  
    ## Layouts
  
    See [Ember.Templates.helpers.yield](/api/classes/Ember.Templates.helpers.html#method_yield)
    for more information.
  
  
    ## Responding to Browser Events
  
    Components can respond to user-initiated events in one of three ways: method
    implementation, through an event manager, and through `{{action}}` helper use
    in their template or layout.
  
  
    ### Method Implementation
  
    Components can respond to user-initiated events by implementing a method that
    matches the event name. A `jQuery.Event` object will be passed as the
    argument to this method.
  
    ```app/components/my-widget.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      click(event) {
        // will be called when an instance's
        // rendered element is clicked
      }
    });
    ```
  
  
    ### `{{action}}` Helper
  
    See [Ember.Templates.helpers.action](/api/classes/Ember.Templates.helpers.html#method_action).
  
  
    ### Event Names
  
    All of the event handling approaches described above respond to the same set
    of events. The names of the built-in events are listed below. (The hash of
    built-in events exists in `Ember.EventDispatcher`.) Additional, custom events
    can be registered by using `Ember.Application.customEvents`.
  
    Touch events:
  
    * `touchStart`
    * `touchMove`
    * `touchEnd`
    * `touchCancel`
  
    Keyboard events:
  
    * `keyDown`
    * `keyUp`
    * `keyPress`
  
    Mouse events:
  
    * `mouseDown`
    * `mouseUp`
    * `contextMenu`
    * `click`
    * `doubleClick`
    * `mouseMove`
    * `focusIn`
    * `focusOut`
    * `mouseEnter`
    * `mouseLeave`
  
    Form events:
  
    * `submit`
    * `change`
    * `focusIn`
    * `focusOut`
    * `input`
  
    HTML5 drag and drop events:
  
    * `dragStart`
    * `drag`
    * `dragEnter`
    * `dragLeave`
    * `dragOver`
    * `dragEnd`
    * `drop`

/**
  Normally, Ember's component model is "write-only". The component takes a
  bunch of attributes that it got passed in, and uses them to render its
  template.
   One nice thing about this model is that if you try to set a value to the
  same thing as last time, Ember (through HTMLBars) will avoid doing any
  work on the DOM.
   This is not just a performance optimization. If an attribute has not
  changed, it is important not to clobber the element's "hidden state".
  For example, if you set an input's `value` to the same value as before,
  it will clobber selection state and cursor position. In other words,
  setting an attribute is not **always** idempotent.
   This method provides a way to read an element's attribute and also
  update the last value Ember knows about at the same time. This makes
  setting an attribute idempotent.
   In particular, what this means is that if you get an `<input>` element's
  `value` attribute and then re-render the template with the same value,
  it will avoid clobbering the cursor and selection position.
  Since most attribute sets are idempotent in the browser, you typically
  can get away with reading attributes using jQuery, but the most reliable
  way to do so is through this method.

  /**
    The `{{link-to}}` component renders a link to the supplied
    `routeName` passing an optionally supplied model to the
    route as its `model` context of the route. The block
    for `{{link-to}}` becomes the innerHTML of the rendered
    element:
  
    ```handlebars
    {{#link-to 'photoGallery'}}
      Great Hamster Photos
    {{/link-to}}
    ```
  
    You can also use an inline form of `{{link-to}}` component by
    passing the link text as the first argument
    to the component:
  
    ```handlebars
    {{link-to 'Great Hamster Photos' 'photoGallery'}}
    ```
  
    Both will result in:
  
    ```html
    <a href="/hamster-photos">
      Great Hamster Photos
    </a>
    ```
  
    ### Supplying a tagName
    By default `{{link-to}}` renders an `<a>` element. This can
    be overridden for a single use of `{{link-to}}` by supplying
    a `tagName` option:
  
    ```handlebars
    {{#link-to 'photoGallery' tagName="li"}}
      Great Hamster Photos
    {{/link-to}}
    ```
  
    ```html
    <li>
      Great Hamster Photos
    </li>
    ```
  
    To override this option for your entire application, see
    "Overriding Application-wide Defaults".
  
    ### Disabling the `link-to` component
    By default `{{link-to}}` is enabled.
    any passed value to the `disabled` component property will disable
    the `link-to` component.
  
    static use: the `disabled` option:
  
    ```handlebars
    {{#link-to 'photoGallery' disabled=true}}
      Great Hamster Photos
    {{/link-to}}
    ```
  
    dynamic use: the `disabledWhen` option:
  
    ```handlebars
    {{#link-to 'photoGallery' disabledWhen=controller.someProperty}}
      Great Hamster Photos
    {{/link-to}}
    ```
  
    any passed value to `disabled` will disable it except `undefined`.
    to ensure that only `true` disable the `link-to` component you can
    override the global behaviour of `Ember.LinkComponent`.
  
    ```javascript
    Ember.LinkComponent.reopen({
      disabled: Ember.computed(function(key, value) {
        if (value !== undefined) {
          this.set('_isDisabled', value === true);
        }
        return value === true ? get(this, 'disabledClass') : false;
      })
    });
    ```
  
    see "Overriding Application-wide Defaults" for more.
  
    ### Handling `href`
    `{{link-to}}` will use your application's Router to
    fill the element's `href` property with a url that
    matches the path to the supplied `routeName` for your
    router's configured `Location` scheme, which defaults
    to Ember.HashLocation.
  
    ### Handling current route
    `{{link-to}}` will apply a CSS class name of 'active'
    when the application's current route matches
    the supplied routeName. For example, if the application's
    current route is 'photoGallery.recent' the following
    use of `{{link-to}}`:
  
    ```handlebars
    {{#link-to 'photoGallery.recent'}}
      Great Hamster Photos
    {{/link-to}}
    ```
  
    will result in
  
    ```html
    <a href="/hamster-photos/this-week" class="active">
      Great Hamster Photos
    </a>
    ```
  
    The CSS class name used for active classes can be customized
    for a single use of `{{link-to}}` by passing an `activeClass`
    option:
  
    ```handlebars
    {{#link-to 'photoGallery.recent' activeClass="current-url"}}
      Great Hamster Photos
    {{/link-to}}
    ```
  
    ```html
    <a href="/hamster-photos/this-week" class="current-url">
      Great Hamster Photos
    </a>
    ```
  
    To override this option for your entire application, see
    "Overriding Application-wide Defaults".
  
    ### Keeping a link active for other routes
  
    If you need a link to be 'active' even when it doesn't match
    the current route, you can use the `current-when` argument.
  
    ```handlebars
    {{#link-to 'photoGallery' current-when='photos'}}
      Photo Gallery
    {{/link-to}}
    ```
  
    This may be helpful for keeping links active for:
  
    * non-nested routes that are logically related
    * some secondary menu approaches
    * 'top navigation' with 'sub navigation' scenarios
  
    A link will be active if `current-when` is `true` or the current
    route is the route this link would transition to.
  
    To match multiple routes 'space-separate' the routes:
  
    ```handlebars
    {{#link-to 'gallery' current-when='photos drawings paintings'}}
      Art Gallery
    {{/link-to}}
    ```
  
    ### Supplying a model
    An optional model argument can be used for routes whose
    paths contain dynamic segments. This argument will become
    the model context of the linked route:
  
    ```javascript
    Router.map(function() {
      this.route("photoGallery", {path: "hamster-photos/:photo_id"});
    });
    ```
  
    ```handlebars
    {{#link-to 'photoGallery' aPhoto}}
      {{aPhoto.title}}
    {{/link-to}}
    ```
  
    ```html
    <a href="/hamster-photos/42">
      Tomster
    </a>
    ```
  
    ### Supplying multiple models
    For deep-linking to route paths that contain multiple
    dynamic segments, multiple model arguments can be used.
    As the router transitions through the route path, each
    supplied model argument will become the context for the
    route with the dynamic segments:
  
    ```javascript
    Router.map(function() {
      this.route("photoGallery", { path: "hamster-photos/:photo_id" }, function() {
        this.route("comment", {path: "comments/:comment_id"});
      });
    });
    ```
    This argument will become the model context of the linked route:
  
    ```handlebars
    {{#link-to 'photoGallery.comment' aPhoto comment}}
      {{comment.body}}
    {{/link-to}}
    ```
  
    ```html
    <a href="/hamster-photos/42/comments/718">
      A+++ would snuggle again.
    </a>
    ```
  
    ### Supplying an explicit dynamic segment value
    If you don't have a model object available to pass to `{{link-to}}`,
    an optional string or integer argument can be passed for routes whose
    paths contain dynamic segments. This argument will become the value
    of the dynamic segment:
  
    ```javascript
    Router.map(function() {
      this.route("photoGallery", { path: "hamster-photos/:photo_id" });
    });
    ```
  
    ```handlebars
    {{#link-to 'photoGallery' aPhotoId}}
      {{aPhoto.title}}
    {{/link-to}}
    ```
  
    ```html
    <a href="/hamster-photos/42">
      Tomster
    </a>
    ```
  
    When transitioning into the linked route, the `model` hook will
    be triggered with parameters including this passed identifier.
  
    ### Allowing Default Action
  
   By default the `{{link-to}}` component prevents the default browser action
   by calling `preventDefault()` as this sort of action bubbling is normally
   handled internally and we do not want to take the browser to a new URL (for
   example).
  
   If you need to override this behavior specify `preventDefault=false` in
   your template:
  
    ```handlebars
    {{#link-to 'photoGallery' aPhotoId preventDefault=false}}
      {{aPhotoId.title}}
    {{/link-to}}
    ```
  
    ### Overriding attributes
    You can override any given property of the `Ember.LinkComponent`
    that is generated by the `{{link-to}}` component by passing
    key/value pairs, like so:
  
    ```handlebars
    {{#link-to  aPhoto tagName='li' title='Following this link will change your life' classNames='pic sweet'}}
      Uh-mazing!
    {{/link-to}}
    ```
  
    See [Ember.LinkComponent](/api/classes/Ember.LinkComponent.html) for a
    complete list of overrideable properties. Be sure to also
    check out inherited properties of `LinkComponent`.
  
    ### Overriding Application-wide Defaults
    ``{{link-to}}`` creates an instance of `Ember.LinkComponent`
    for rendering. To override options for your entire
    application, reopen `Ember.LinkComponent` and supply the
    desired values:
  
    ``` javascript
    Ember.LinkComponent.reopen({
      activeClass: "is-active",
      tagName: 'li'
    })
    ```
  
    It is also possible to override the default event in
    this manner:
  
    ``` javascript
    Ember.LinkComponent.reopen({
      eventName: 'customEventName'
    });
    ```
  
    @method link-to
    @for Ember.Templates.helpers
    @param {String} routeName
    @param {Object} [context]*
    @param [options] {Object} Handlebars key/value pairs of options, you can override any property of Ember.LinkComponent

    `{{textarea}}` inserts a new instance of `<textarea>` tag into the template.
    The attributes of `{{textarea}}` match those of the native HTML tags as
    closely as possible.
  
    The following HTML attributes can be set:
  
      * `value`
      * `name`
      * `rows`
      * `cols`
      * `placeholder`
      * `disabled`

      * `readonly`
      * `autofocus`
      * `form`
      * `spellcheck`
      * `required`
  
    When set to a quoted string, these value will be directly applied to the HTML
    element. When left unquoted, these values will be bound to a property on the
    template's current rendering context (most typically a controller instance).
  
    Unbound:
  
    ```handlebars
    {{textarea value="Lots of static text that ISN'T bound"}}
    ```
  
    Would result in the following HTML:
  
    ```html
    <textarea class="ember-text-area">
      Lots of static text that ISN'T bound
    </textarea>
    ```
  
    Bound:
  
    In the following example, the `writtenWords` property on `App.ApplicationController`
    will be updated live as the user types 'Lots of text that IS bound' into
    the text area of their browser's window.
  
    ```javascript
    App.ApplicationController = Ember.Controller.extend({
      writtenWords: "Lots of text that IS bound"
    });
    ```
  
    ```handlebars
    {{textarea value=writtenWords}}
    ```
  
     Would result in the following HTML:
  
    ```html
    <textarea class="ember-text-area">
      Lots of text that IS bound
    </textarea>
    ```
  
    If you wanted a one way binding between the text area and a div tag
    somewhere else on your screen, you could use `Ember.computed.oneWay`:
  
    ```javascript
    App.ApplicationController = Ember.Controller.extend({
      writtenWords: "Lots of text that IS bound",
      outputWrittenWords: Ember.computed.oneWay("writtenWords")
    });
    ```
  
    ```handlebars
    {{textarea value=writtenWords}}
    <div>
      {{outputWrittenWords}}
    </div>
    ```
  
    Would result in the following HTML:
  
    ```html
    <textarea class="ember-text-area">
      Lots of text that IS bound
    </textarea>
    <-- the following div will be updated in real time as you type -->
    <div>
      Lots of text that IS bound
    </div>
    ```
  
    Finally, this example really shows the power and ease of Ember when two
    properties are bound to eachother via `Ember.computed.alias`. Type into
    either text area box and they'll both stay in sync. Note that
    `Ember.computed.alias` costs more in terms of performance, so only use it when
    your really binding in both directions:
  
    ```javascript
    App.ApplicationController = Ember.Controller.extend({
      writtenWords: "Lots of text that IS bound",
      twoWayWrittenWords: Ember.computed.alias("writtenWords")
    });
    ```
  
    ```handlebars
    {{textarea value=writtenWords}}
    {{textarea value=twoWayWrittenWords}}
    ```
  
    ```html
    <textarea id="ember1" class="ember-text-area">
      Lots of text that IS bound
    </textarea>
    <-- both updated in real time -->
    <textarea id="ember2" class="ember-text-area">
      Lots of text that IS bound
    </textarea>
    ```
  
    ### Actions
  
    The helper can send multiple actions based on user events.
    The action property defines the action which is send when
    the user presses the return key.
  
    ```handlebars
    {{input action="submit"}}
    ```
  
    The helper allows some user events to send actions.
  
    * `enter`
    * `insert-newline`
    * `escape-press`
    * `focus-in`
    * `focus-out`
    * `key-press`
  
    For example, if you desire an action to be sent when the input is blurred,
    you only need to setup the action name to the event name property.
  
    ```handlebars
    {{textarea focus-out="alertMessage"}}
    ```
  
    See more about [Text Support Actions](/api/classes/Ember.TextArea.html)
  
    ### Extension
  
    Internally, `{{textarea}}` creates an instance of `Ember.TextArea`, passing
    arguments from the helper to `Ember.TextArea`'s `create` method. You can
    extend the capabilities of text areas in your application by reopening this
    class. For example, if you are building a Bootstrap project where `data-*`
    attributes are used, you can globally add support for a `data-*` attribute
    on all `{{textarea}}`s' in your app by reopening `Ember.TextArea` or
    `Ember.TextSupport` and adding it to the `attributeBindings` concatenated
    property:
  
    ```javascript
    Ember.TextArea.reopen({
      attributeBindings: ['data-error']
    });
    ```
  
    Keep in mind when writing `Ember.TextArea` subclasses that `Ember.TextArea`
    itself extends `Ember.Component`. Expect isolated component semantics, not
    legacy 1.x view semantics (like `controller` being present).

    Ember Helpers are functions that can compute values, and are used in templates.
    For example, this code calls a helper named `format-currency`:
  
    ```handlebars
    <div>{{format-currency cents currency="$"}}</div>
    ```
  
    Additionally a helper can be called as a nested helper (sometimes called a
    subexpression). In this example, the computed value of a helper is passed
    to a component named `show-money`:
  
    ```handlebars
    {{show-money amount=(format-currency cents currency="$")}}
    ```
  
    Helpers defined using a class must provide a `compute` function. For example:
  
    ```js
    export default Ember.Helper.extend({
      compute(params, hash) {
        let cents = params[0];
        let currency = hash.currency;
        return `${currency}${cents * 0.01}`;
      }
    });
    ```
  
    Each time the input to a helper changes, the `compute` function will be
    called again.
  
    As instances, these helpers also have access to the container an will accept
    injected dependencies.
  
    Additionally, class helpers can call `recompute` to force a new computation.

    The `{{action}}` helper provides a way to pass triggers for behavior (usually
    just a function) between components, and into components from controllers.
  
    ### Passing functions with the action helper
  
    There are three contexts an action helper can be used in. The first two
    contexts to discuss are attribute context, and Handlebars value context.
  
    ```handlebars
    {{! An example of attribute context }}
    <div onclick={{action "save"}}></div>
    {{! Examples of Handlebars value context }}
    {{input on-input=(action "save")}}
    {{yield (action "refreshData") andAnotherParam}}
    ```
  
    In these contexts,
    the helper is called a "closure action" helper. Its behavior is simple:
    If passed a function name, read that function off the `actions` property
    of the current context. Once that function is read (or if a function was
    passed), create a closure over that function and any arguments.
    The resulting value of an action helper used this way is simply a function.
  
    For example, in the attribute context:
  
    ```handlebars
    {{! An example of attribute context }}
    <div onclick={{action "save"}}></div>
    ```
  
    The resulting template render logic would be:
  
    ```js
    var div = document.createElement('div');
    var actionFunction = (function(context){
      return function() {
        return context.actions.save.apply(context, arguments);
      };
    })(context);
    div.onclick = actionFunction;
    ```
  
    Thus when the div is clicked, the action on that context is called.
    Because the `actionFunction` is just a function, closure actions can be
    passed between components and still execute in the correct context.
  
    Here is an example action handler on a component:
  
    ```js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      actions: {
        save() {
          this.get('model').save();
        }
      }
    });
    ```
  
    Actions are always looked up on the `actions` property of the current context.
    This avoids collisions in the naming of common actions, such as `destroy`.
    Two options can be passed to the `action` helper when it is used in this way.
  
    * `target=someProperty` will look to `someProperty` instead of the current
      context for the `actions` hash. This can be useful when targetting a
      service for actions.
    * `value="target.value"` will read the path `target.value` off the first
      argument to the action when it is called and rewrite the first argument
      to be that value. This is useful when attaching actions to event listeners.
  
    ### Invoking an action
  
    Closure actions curry both their scope and any arguments. When invoked, any
    additional arguments are added to the already curried list.
    Actions should be invoked using the [sendAction](/api/classes/Ember.Component.html#method_sendAction)
    method. The first argument to `sendAction` is the action to be called, and
    additional arguments are passed to the action function. This has interesting
    properties combined with currying of arguments. For example:
  
    ```js
    export default Ember.Component.extend({
      actions: {
        // Usage {{input on-input=(action (action 'setName' model) value="target.value")}}
        setName(model, name) {
          model.set('name', name);
        }
      }
    });
    ```
  
    The first argument (`model`) was curried over, and the run-time argument (`event`)
    becomes a second argument. Action calls can be nested this way because each simply
    returns a function. Any function can be passed to the `{{action}}` helper, including
    other actions.
  
    Actions invoked with `sendAction` have the same currying behavior as demonstrated
    with `on-input` above. For example:
  
    ```app/components/my-input.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      actions: {
        setName(model, name) {
          model.set('name', name);
        }
      }
    });
    ```
  
    ```handlebars
    {{my-input submit=(action 'setName' model)}}
    ```
  
    ```app/components/my-component.js
    import Ember from 'ember';
  
    export default Ember.Component.extend({
      click() {
        // Note that model is not passed, it was curried in the template
        this.sendAction('submit', 'bob');
      }
    });
    ```
  
    ### Attaching actions to DOM elements
  
    The third context of the `{{action}}` helper can be called "element space".
    For example:
  
    ```handlebars
    {{! An example of element space }}
    <div {{action "save"}}></div>
    ```
  
    Used this way, the `{{action}}` helper provides a useful shortcut for
    registering an HTML element in a template for a single DOM event and
    forwarding that interaction to the template's context (controller or component).
    If the context of a template is a controller, actions used this way will
    bubble to routes when the controller does not implement the specified action.
    Once an action hits a route, it will bubble through the route hierarchy.
  
    ### Event Propagation
  
    `{{action}}` helpers called in element space can control event bubbling. Note
    that the closure style actions cannot.
  
    Events triggered through the action helper will automatically have
    `.preventDefault()` called on them. You do not need to do so in your event
    handlers. If you need to allow event propagation (to handle file inputs for
    example) you can supply the `preventDefault=false` option to the `{{action}}` helper:
  
    ```handlebars
    <div {{action "sayHello" preventDefault=false}}>
      <input type="file" />
      <input type="checkbox" />
    </div>
    ```
  
    To disable bubbling, pass `bubbles=false` to the helper:
  
    ```handlebars
    <button {{action 'edit' post bubbles=false}}>Edit</button>
    ```
  
    To disable bubbling with closure style actions you must create your own
    wrapper helper that makes use of `event.stopPropagation()`:
  
    ```handlebars
    <div onclick={{disable-bubbling (action "sayHello")}}>Hello</div>
    ```
  
    ```app/helpers/disable-bubbling.js
    import Ember from 'ember';
  
    export function disableBubbling([action]) {
      return function(event) {
        event.stopPropagation();
        return action(event);
      };
    }
    export default Ember.Helper.helper(disableBubbling);
    ```
  
    If you need the default handler to trigger you should either register your
    own event handler, or use event methods on your view class. See
    ["Responding to Browser Events"](/api/classes/Ember.View.html#toc_responding-to-browser-events)
    in the documentation for Ember.View for more information.
  
    ### Specifying DOM event type
  
    `{{action}}` helpers called in element space can specify an event type.
    By default the `{{action}}` helper registers for DOM `click` events. You can
    supply an `on` option to the helper to specify a different DOM event name:
  
    ```handlebars
    <div {{action "anActionName" on="doubleClick"}}>
      click me
    </div>
    ```
  
    See ["Event Names"](/api/classes/Ember.View.html#toc_event-names) for a list of
    acceptable DOM event names.
  
    ### Specifying whitelisted modifier keys
  
    `{{action}}` helpers called in element space can specify modifier keys.
    By default the `{{action}}` helper will ignore click events with pressed modifier
    keys. You can supply an `allowedKeys` option to specify which keys should not be ignored.
  
    ```handlebars
    <div {{action "anActionName" allowedKeys="alt"}}>
      click me
    </div>
    ```
  
    This way the action will fire when clicking with the alt key pressed down.
    Alternatively, supply "any" to the `allowedKeys` option to accept any combination of modifier keys.
  
    ```handlebars
    <div {{action "anActionName" allowedKeys="any"}}>
      click me with any key pressed
    </div>
    ```
  
    ### Specifying a Target
  
    A `target` option can be provided to the helper to change
    which object will receive the method call. This option must be a path
    to an object, accessible in the current context:
  
    ```app/templates/application.hbs
    <div {{action "anActionName" target=someService}}>
      click me
    </div>
    ```
  
    ```app/controllers/application.js
    import Ember from 'ember';
  
    export default Ember.Controller.extend({
      someService: Ember.inject.service()
    });
    ```

    The `{{component}}` helper lets you add instances of `Ember.Component` to a
    template. See [Ember.Component](/api/classes/Ember.Component.html) for
    additional information on how a `Component` functions.
    `{{component}}`'s primary use is for cases where you want to dynamically
    change which type of component is rendered as the state of your application
    changes. This helper has three modes: inline, block, and nested.
  
    ### Inline Form
  
    Given the following template:
  
    ```app/application.hbs
    {{component infographicComponentName}}
    ```
  
    And the following application code:
  
    ```app/controllers/application.js
    export default Ember.Controller.extend({
      infographicComponentName: computed('isMarketOpen', {
        get() {
          if (this.get('isMarketOpen')) {
            return 'live-updating-chart';
          } else {
            return 'market-close-summary';
          }
        }
      })
    });
    ```
  
    The `live-updating-chart` component will be appended when `isMarketOpen` is
    `true`, and the `market-close-summary` component will be appended when
    `isMarketOpen` is `false`. If the value changes while the app is running,
    the component will be automatically swapped out accordingly.
    Note: You should not use this helper when you are consistently rendering the same
    component. In that case, use standard component syntax, for example:
  
    ```app/templates/application.hbs
    {{live-updating-chart}}
    ```
  
    ### Block Form
  
    Using the block form of this helper is similar to using the block form
    of a component. Given the following application template:
  
    ```app/templates/application.hbs
    {{#component infographicComponentName}}
      Last update: {{lastUpdateTimestamp}}
    {{/component}}
    ```
  
    The following controller code:
  
    ```app/controllers/application.js
    export default Ember.Controller.extend({
      lastUpdateTimestamp: computed(function() {
        return new Date();
      }),
  
      infographicComponentName: computed('isMarketOpen', {
        get() {
          if (this.get('isMarketOpen')) {
            return 'live-updating-chart';
          } else {
            return 'market-close-summary';
          }
        }
      })
    });
    ```
  
    And the following component template:
  
    ```app/templates/components/live-updating-chart.hbs
    {{! chart }}
    {{yield}}
    ```
  
    The `Last Update: {{lastUpdateTimestamp}}` will be rendered in place of the `{{yield}}`.
  
    ### Nested Usage
  
    The `component` helper can be used to package a component path with initial attrs.
    The included attrs can then be merged during the final invocation.
    For example, given a `person-form` component with the following template:
  
    ```app/templates/components/person-form.hbs
    {{yield (hash
      nameInput=(component "my-input-component" value=model.name placeholder="First Name")
    )}}
    ```
  
    When yielding the component via the `hash` helper, the component is invoked directly.
    See the following snippet:
  
    ```
    {{#person-form as |form|}}
      {{form.nameInput placeholder="Username"}}
    {{/person-form}}
    ```
  
    Which outputs an input whose value is already bound to `model.name` and `placeholder`
    is "Username".
  
    When yielding the component without the hash helper use the `component` helper.
    For example, below is a `full-name` component template:
  
    ```handlebars
    {{yield (component "my-input-component" value=model.name placeholder="Name")}}
    ```
  
    ```
    {{#full-name as |field|}}
      {{component field placeholder="Full name"}}
    {{/full-name}}
    ```

  /**
    The `{{#each}}` helper loops over elements in a collection. It is an extension
    of the base Handlebars `{{#each}}` helper.
    The default behavior of `{{#each}}` is to yield its inner block once for every
    item in an array passing the item as the first block parameter.
  
    ```javascript
    var developers = [{ name: 'Yehuda' },{ name: 'Tom' }, { name: 'Paul' }];
    ```
  
    ```handlebars
    {{#each developers key="name" as |person|}}
      {{person.name}}
      {{! `this` is whatever it was outside the #each }}
    {{/each}}
    ```
  
    The same rules apply to arrays of primitives.
  
    ```javascript
    var developerNames = ['Yehuda', 'Tom', 'Paul']
    ```
  
    ```handlebars
    {{#each developerNames key="@index" as |name|}}
      {{name}}
    {{/each}}
    ```
  
    During iteration, the index of each item in the array is provided as a second block parameter.
  
    ```handlebars
    <ul>
      {{#each people as |person index|}}
        <li>Hello, {{person.name}}! You're number {{index}} in line</li>
      {{/each}}
    </ul>
    ```
  
    ### Specifying Keys
  
    The `key` option is used to tell Ember how to determine if the array being
    iterated over with `{{#each}}` has changed between renders. By helping Ember
    detect that some elements in the array are the same, DOM elements can be
    re-used, significantly improving rendering speed.
  
    For example, here's the `{{#each}}` helper with its `key` set to `id`:
  
    ```handlebars
    {{#each model key="id" as |item|}}
    {{/each}}
    ```
  
    When this `{{#each}}` re-renders, Ember will match up the previously rendered
    items (and reorder the generated DOM elements) based on each item's `id`
    property.
    By default the item's own reference is used.
  
    ### {{else}} condition
  
    `{{#each}}` can have a matching `{{else}}`. The contents of this block will render
    if the collection is empty.
  
    ```handlebars
    {{#each developers as |person|}}
      {{person.name}}
    {{else}}
      <p>Sorry, nobody is available for this task.</p>
    {{/each}}
    ```

    Dynamically look up a property on an object. The second argument to `{{get}}`

    For example, these two usages are equivilent:
  
    ```handlebars
    {{person.height}}
    {{get person "height"}}
    ```
  
    If there were several facts about a person, the `{{get}}` helper can dynamically
    pick one:
  
    ```handlebars
    {{get person factName}}
    ```
  
    For a more complex example, this template would allow the user to switch
    between showing the user's height and weight with a click:
  
    ```handlebars
    {{get person factName}}
    <button {{action (action (mut factName)) "height"}}>Show height</button>
    <button {{action (action (mut factName)) "weight"}}>Show weight</button>
    ```
  
    The `{{get}}` helper can also respect mutable values itself. For example:
  
    ```handlebars
    {{input value=(mut (get person factName)) type="text"}}
    <button {{action (action (mut factName)) "height"}}>Show height</button>
    <button {{action (action (mut factName)) "weight"}}>Show weight</button>
    ```
  
    Would allow the user to swap what fact is being displayed, and also edit
    that fact via a two-way mutable binding.

  /**
    The `mut` helper lets you __clearly specify__ that a child `Component` can update the
    (mutable) value passed to it, which will __change the value of the parent component__.
  
    To specify that a parameter is mutable, when invoking the child `Component`:
  
    ```handlebars
    {{my-child childClickCount=(mut totalClicks)}}
    ```
  
    The child `Component` can then modify the parent's value just by modifying its own
    property:
  
    ```javascript
    // my-child.js
    export default Component.extend({
      click() {
        this.incrementProperty('childClickCount');
      }
    });
    ```
  
    Note that for curly components (`{{my-component}}`) the bindings are already mutable,
    making the `mut` unnecessary.
  
    Additionally, the `mut` helper can be combined with the `action` helper to
    mutate a value. For example:
  
    ```handlebars
    {{my-child childClickCount=totalClicks click-count-change=(action (mut totalClicks))}}
    ```
  
    The child `Component` would invoke the action with the new click value:
  
    ```javascript
    // my-child.js
    export default Component.extend({
      click() {
        this.get('click-count-change')(this.get('childClickCount') + 1);
      }
    });
    ```
  
    The `mut` helper changes the `totalClicks` value to what was provided as the action argument.
  
    The `mut` helper, when used with `action`, will return a function that
    sets the value passed to `mut` to its first argument. This works like any other
    closure action and interacts with the other features `action` provides.
    As an example, we can create a button that increments a value passing the value
    directly to the `action`:
  
    ```handlebars
    {{! inc helper is not provided by Ember }}
    <button onclick={{action (mut count) (inc count)}}>
      Increment count
    </button>
    ```
  
    You can also use the `value` option:
  
    ```handlebars
    <input value={{name}} oninput={{action (mut name) value="target.value"}}>
    ```
  
    @method mut
    @param {Object} [attr] the "two-way" attribute that can be modified.

  /**
    The `readonly` helper let's you specify that a binding is one-way only,
    instead of two-way.
    When you pass a `readonly` binding from an outer context (e.g. parent component),
    to to an inner context (e.g. child component), you are saying that changing that
    property in the inner context does not change the value in the outer context.
  
    To specify that a binding is read-only, when invoking the child `Component`:
  
    ```app/components/my-parent.js
    export default Component.extend({
      totalClicks: 3
    });
    ```
  
    ```app/templates/components/my-parent.hbs
    {{log totalClicks}} // -> 3
    {{my-child childClickCount=(readonly totalClicks)}}
    ```
  
    Now, when you update `childClickCount`:
  
    ```app/components/my-child.js
    export default Component.extend({
      click() {
        this.incrementProperty('childClickCount');
      }
    });
    ```
  
    The value updates in the child component, but not the parent component:
  
    ```app/templates/components/my-child.hbs
    {{log childClickCount}} //-> 4
    ```
  
    ```app/templates/components/my-parent.hbs
    {{log totalClicks}} //-> 3
    {{my-child childClickCount=(readonly totalClicks)}}
    ```
  
    ### Objects and Arrays
  
    When passing a property that is a complex object (e.g. object, array) instead of a primitive object (e.g. number, string),
    only the reference to the object is protected using the readonly helper.
    This means that you can change properties of the object both on the parent component, as well as the child component.
    The `readonly` binding behaves similar to the `const` keyword in JavaScript.
  
    Let's look at an example:
  
    First let's set up the parent component:
  
    ```app/components/my-parent.js
    export default Ember.Component.extend({
      clicks: null,
  
      init() {
        this._super(...arguments);
        this.set('clicks', { total: 3 });
      }
    });
    ```
  
    ```app/templates/components/my-parent.hbs
    {{log clicks.total}} //-> 3
    {{my-child childClicks=(readonly clicks)}}
    ```
  
    Now, if you update the `total` property of `childClicks`:
  
    ```app/components/my-child.js
    export default Ember.Component.extend({
      click() {
        this.get('clicks').incrementProperty('total');
      }
    });
    ```
  
    You will see the following happen:
  
    ```app/templates/components/my-parent.hbs
    {{log clicks.total}} //-> 4
    {{my-child childClicks=(readonly clicks)}}
    ```
  
    ```app/templates/components/my-child.hbs
    {{log childClicks.total}} //-> 4
    ```
  
    @method readonly
    @param {Object} [attr] the read-only attribute.
    @for Ember.Templates.helpers
    @private
  */

  /**
    [Glimmer](https://github.com/tildeio/glimmer) is a templating engine used by Ember.js that is compatible with a subset of the [Handlebars](http://handlebarsjs.com/) syntax.
  
    ### Showing a property
  
    Templates manage the flow of an application's UI, and display state (through
    the DOM) to a user. For example, given a component with the property "name",
    that component's template can use the name in several ways:
  
    ```app/components/person.js
      export default Ember.Component.extend({
        name: 'Jill'
      });
    ```
  
    ```app/components/person.hbs
    {{name}}
    <div>{{name}}</div>
    <span data-name={{name}}></span>
    ```
  
    Any time the "name" property on the component changes, the DOM will be
    updated.
  
    Properties can be chained as well:
  
    ```handlebars
    {{aUserModel.name}}
    <div>{{listOfUsers.firstObject.name}}</div>
    ```
  
    ### Using Ember helpers
  
    When content is passed in mustaches `{{}}`, Ember will first try to find a helper
    or component with that name. For example, the `if` helper:
  
    ```handlebars
    {{if name "I have a name" "I have no name"}}
    <span data-has-name={{if name true}}></span>
    ```
  
    The returned value is placed where the `{{}}` is called. The above style is
    called "inline". A second style of helper usage is called "block". For example:
  
    ```handlebars
    {{#if name}}
    I have a name
    {{else}}
    I have no name
    {{/if}}
    ```
  
    The block form of helpers allows you to control how the UI is created based
    on the values of properties.
    A third form of helper is called "nested". For example here the concat
    helper will add " Doe" to a displayed name if the person has no last name:
  
    ```handlebars
    <span data-name={{concat firstName (
    if lastName (concat " " lastName) "Doe"
    )}}></span>
    ```
  
    Ember's built-in helpers are described under the [Ember.Templates.helpers](/api/classes/Ember.Templates.helpers.html)
    namespace. Documentation on creating custom helpers can be found under
    [Ember.Helper](/api/classes/Ember.Helper.html).
  
    ### Invoking a Component
  
    Ember components represent state to the UI of an application. Further
    reading on components can be found under [Ember.Component](/api/classes/Ember.Component.html).
  
    @module ember
    @submodule ember-glimmer
    @main ember-glimmer
    @public

  /**
    Use the `{{with}}` helper when you want to alias a property to a new name. This is helpful
    for semantic clarity as it allows you to retain default scope or to reference a property from another
    `{{with}}` block.
  
    If the aliased property is "falsey", for example: `false`, `undefined` `null`, `""`, `0`, NaN or
    an empty array, the block will not be rendered.
  
    ```handlebars
    {{! Will only render if user.posts contains items}}
    {{#with user.posts as |blogPosts|}}
      <div class="notice">
        There are {{blogPosts.length}} blog posts written by {{user.name}}.
      </div>
      {{#each blogPosts as |post|}}
        <li>{{post.title}}</li>
      {{/each}}
    {{/with}}
    ```
  
    Without the `as` operator, it would be impossible to reference `user.name` in the example above.
  
    NOTE: The alias should not reuse a name from the bound property path.
  
    For example: `{{#with foo.bar as |foo|}}` is not supported because it attempts to alias using
    the first part of the property path, `foo`. Instead, use `{{#with foo.bar as |baz|}}`.

  /**
    Execute the `debugger` statement in the current template's context.
  
    ```handlebars
    {{debugger}}
    ```
  
    When using the debugger helper you will have access to a `get` function. This
    function retrieves values available in the context of the template.
    For example, if you're wondering why a value `{{foo}}` isn't rendering as
    expected within a template, you could place a `{{debugger}}` statement and,
    when the `debugger;` breakpoint is hit, you can attempt to retrieve this value:
  
    ```
    > get('foo')
    ```
  
    `get` is also aware of keywords. So in this situation
  
    ```handlebars
    {{#each items as |item|}}
      {{debugger}}
    {{/each}}
    ```
  
    You'll be able to get values from the current item:
  
    ```
    > get('item.name')
    ```
  
    You can also access the context of the view to make sure it is the object that
    you expect:
  
    ```
    > context
    ```
  
    @method debugger
    @for Ember.Templates.helpers

  /**
    The `partial` helper renders another template without
    changing the template context:
  
    ```handlebars
    {{foo}}
    {{partial "nav"}}
    ```
  
    The above example template will render a template named
    "-nav", which has the same context as the parent template
    it's rendered into, so if the "-nav" template also referenced
    `{{foo}}`, it would print the same thing as the `{{foo}}`
    in the above example.
  
    If a "-nav" template isn't found, the `partial` helper will
    fall back to a template named "nav".
  
    ### Bound template names
  
    The parameter supplied to `partial` can also be a path
    to a property containing a template name, e.g.:
  
    ```handlebars
    {{partial someTemplateName}}
    ```
  
    The above example will look up the value of `someTemplateName`
    on the template context (e.g. a controller) and use that
    value as the name of the template to render. If the resolved
    value is falsy, nothing will be rendered. If `someTemplateName`
    changes, the partial will be re-rendered using the new template
    name.
