// Instructions: Take 3x passes w/ notes each time
// #.1: no console / no stackoverflow
// #.2: use console / no stackoverflow
// #.3: use console / use stackoverflow

// end result should look like: 
// 1) How could you rewrite \n`{abc(xyz)}`?
// 1.1) I'd remove xyz like \n`abc()`
// 1.2) Confirmed works in console but needed to run it \n`abc()`
// 1.3) Googled and found this different approach I'd like more \n`if (!xyz) abc()}` (link to article / answer)

// 1: how could you rewrite the following to make it shorter?
if (foo) {
  bar.doSomething(el);
} else {
  bar.doSomethingElse(el);
}




// 2: a) what does the following code log?
// 2: b) how could you log the other variable and still maintain the optional fallback logic?

var foo = 'logme';

(function() {
  var foo = foo || 'fallback';
  console.log(foo);
})();




// 3: given the following code, how would you override the value of the bar
// property for the variable foo without affecting the value of the bar
// property for the variable bim? how would you affect the value of the bar
// property for both foo and bim? how would you add a method to foo and bim to
// console.log the value of each object's bar property? how would you tell if
// the object's bar property had been overridden for the particular object?
var Thinger = function() {
  return this;
};

Thinger.prototype = {
  bar : 'baz'
};

var foo = new Thinger(),
    bim = new Thinger();




// 4: given the following code, and assuming that each defined object has a
// 'destroy' method, how would you destroy all of the objects contained in the
// myObjects object?
var myObjects = {
  thinger : new myApp.Thinger(),
  gizmo : new myApp.Gizmo(),
  widget : new myApp.Widget()
};




// 5: given the following array, create an array that contains the contents of
// each array item repeated three times, with a space between each item. so,
// for example, if an array item is 'foo' then the new array should contain an
// array item 'foo foo foo'. (you can assume the library of your choice is
// available)
var myArray = [ 'foo', 'bar', 'baz' ];




// 6: a) How could you improve the following code? 
// 6: b) What assuptions did you make in your improvement?
// 6: c) What would you ask around requirements / comments to help clarify those assumptions?
$(document).ready(function() {
  $('.foo #bar').css('color', 'red');
  $('.foo #bar').css('border', '1px solid blue');
  $('.foo #bar').text('new text!');
  $('.foo #bar').click(function() {
    $(this).attr('title', 'new title');
    $(this).width('100px');
  });
  
  $('.foo #bar').click();
});




// 7: what issues do you see with the following code? how would you fix it?
(function() {
  var foo;

  $.get({
    url : 'foo.php',
    success : function(resp) {
      foo = resp.foo;
    }
  });

  if (foo) {
    // run this important code
  }
})();




// 8: how could you rewrite the following code to make it shorter?
(function($){
  $('li.foo a').attr('title', 'i am foo');
  $('li.bar a').attr('title', 'i am bar');
  $('li.baz a').attr('title', 'i am baz');
  $('li.bop a').attr('title', 'i am bop');
})(window.jQuery);



// 9: b) what's non-performant about the following code?
// 9: c) how would you DRY up the code below?
for (i = 0; i <= 100; i++) {
  $('#thinger').append('<p><span class="thinger">i am thinger ' + i + '</span></p>');
  $('#gizmo').append('<p><span class="gizmo">i am gizmo ' + i + '</span></p>');
}


// 10: given the following data structure, write code that returns an array 
// containing the name of each item, followed by a comma-separated list of
// the item's extras, if it has any. e.g. 
//
//    [ "Salad (Chicken, Steak, Shrimp)", ... ]
//
// (you can assume the library of your choice is available)
var menuItems = [
  { id : 1, name : 'Salad', extras : [ 'Chicken', 'Steak', 'Shrimp' ] },
  { id : 2, name : 'Potato', extras : [ 'Bacon', 'Sour Cream', 'Shrimp' ] },
  { id : 3, name : 'Sandwich', extras : [ 'Turkey', 'Bacon' ] },
  { id : 4, name : 'Bread' }
];



// BONUS: write code such that the following alerts "Hello World"
say('Hello')('World');
