Adds an object to an array. If the array already includes the object this method has no effect.

Calls the filter function on the passed object with a specified callback. This uses Ember.ArrayPolyfill's-filter method when necessary.

Calls the forEach function on the passed object with a specified callback. This uses Ember.ArrayPolyfill's-forEach method when necessary.

Returns an array of indexes of the first occurrences of the passed elements on the passed object.

 var array = [1, 2, 3, 4, 5];
 Ember.EnumerableUtils.indexesOf(array, [2, 5]); // [1, 4]

 var fubar = "Fubarr";
 Ember.EnumerableUtils.indexesOf(fubar, ['b', 'r']); // [2, 4]

Calls the indexOf function on the passed object with a specified callback. This uses Ember.ArrayPolyfill's-indexOf method when necessary.

Calculates the intersection of two arrays. This method returns a new array filled with the records that the two passed arrays share with each other. If there is no intersection, an empty array will be returned.

var array1 = [1, 2, 3, 4, 5];
var array2 = [1, 3, 5, 6, 7];

Ember.EnumerableUtils.intersection(array1, array2); // [1, 3, 5]

var array1 = [1, 2, 3];
var array2 = [4, 5, 6];

Ember.EnumerableUtils.intersection(array1, array2); // []

Calls the map function on the passed object with a specified callback. This uses Ember.ArrayPolyfill's-map method when necessary.

Removes an object from an array. If the array does not contain the passed object this method has no effect.

Replaces objects in an array with the passed objects.

  var array = [1,2,3];
  Ember.EnumerableUtils.replace(array, 1, 2, [4, 5]); // [1, 4, 5]

  var array = [1,2,3];
  Ember.EnumerableUtils.replace(array, 1, 1, [4, 5]); // [1, 4, 5, 3]

  var array = [1,2,3];
  Ember.EnumerableUtils.replace(array, 10, 1, [4, 5]); // [1, 2, 3, 4, 5]
