Components are taking center stage in Ember 2.0. Here are some things you can do today to make the transition as smooth as possible:

Use Ember CLI
In general, replace views + controllers with components
Only use controllers at the top-level for receiving data from the route, and use Ember.Controller instead of Ember.ArrayController or Ember.ObjectController
Fetch data in your route, and set it on attrs on your top-level controller:
```
```js   
//controllers/index.js
import Ember from 'ember';
```

  git pull
  git checkout -b branch/name
  git pull -u origin branch/name

Then create a pull request.Once your pull request is reviewed and merged to the master do the following.

 git branch -d branch/name

	function coordinates(x, y, callback) {
	callback(x, y);
	}

	coordinates(10, 20, function(x, y){
	console.log(x + y);
	});

	Promise.resolve().then(function () {
	return 100;
	})
	.then(function() {
	console.log(arguments);
	});

	// ---

	Promise.resolve(200).then(function () {

	jQuery = {

	get: function(url, callback) {
	// do some XHR and get response back from the server

	if (response.status === 200) {
	callback(response.data);
	}
	}
	}

	// Examples you can try in the Dev tools.
	// Aim for these examples to demonstrate different ways of using promises

	var p = Promise.resolve().then(function(){
	console.log('Promise resolve callback');
	}, function(){
	console.log('Promise reject callback');
	});

	var p = Promise.reject().then(function(){

	function close () {
	return 'To End the meeting correctly, please click Stay on this page and then click the Exit Button at the bottom of this page';
	}
	window.onbeforeunload = close;
