 Class ArrayProxy public   Extends: EmberObject   Uses:  MutableArray    Defined in:  packages/ember-runtime/lib/system/array_proxy.js:33    Module: @ember/array    addArrayObserver  (target, opts)  EmberArray public    Module: @ember/array    Inherited from  EmberArray packages/ember-runtime/lib/mixins/array.js:453    target Object The observer object. opts Object Optional hash of configuration options including `willChange` and `didChange` option. returns EmberArray receiver  Adds an array observer to the receiving array. The array observer object normally must implement two methods:  
arrayWillChange(observedObj, start, removeCount, addCount) - This method will be called just before the array is modified. 
arrayDidChange(observedObj, start, removeCount, addCount) - This method will be called just after the array is modified.  Both callbacks will be passed the observed object, starting index of the change as well as a count of the items to be removed and added. You can use these callbacks to optionally inspect the array during the change, clear caches, or do any other bookkeeping necessary. In addition to passing a target, you can also include an options hash which you can use to override the method names that will be invoked on the target.  addObject  (object)  Object public    Module: @ember/array    Inherited from  Ember.MutableEnumerable packages/ember-runtime/lib/mixins/mutable_enumerable.js:54    object Object The object to add to the enumerable. returns Object the passed object  Required. You must implement this method to apply this mixin. Attempts to add the passed object to the receiver if the object is not already present in the collection. If the object is present, this method has no effect. If the passed object is of a type not supported by the receiver, then this method should raise an exception.  addObjects  (objects)  Object public    Module: @ember/array    Inherited from  Ember.MutableEnumerable packages/ember-runtime/lib/mixins/mutable_enumerable.js:71    objects Ember.Enumerable the objects to add. returns Object receiver  Adds each object in the passed enumerable to the receiver.  addObserver  (key, target, method)  Ember.Observable public    Module: @ember/array    Inherited from  Observable packages/ember-runtime/lib/mixins/observable.js:331    key String The key to observe target Object The target object to invoke method String|Function The method to invoke returns Ember.Observable  Adds an observer on a property. This is the core method used to register an observer for a property. Once you call this method, any time the key's value is set, your observer will be notified. Note that the observers are triggered any time the value is set, regardless of whether it has actually changed. Your observer should be prepared to handle that. Observer Methods Observer methods have the following signature: component.js
import Component from '@ember/component';

export default Component.extend({
  init() {
    this._super(...arguments);
    this.addObserver('foo', this, 'fooDidChange');
  },

  fooDidChange(sender, key, value, rev) {
    // your code
  }
}); The sender is the object that changed. The key is the property that changes. The value property is currently reserved and unused. The rev is the last property revision of the object when it changed, which you can use to detect if the key value has really changed or not. Usually you will not need the value or revision parameters at the end. In this case, it is common to write observer methods that take only a sender and key value as parameters or, if you aren't interested in any of these values, to write an observer that has no ronaldfernandez@example.org.  any  (callback, target)  Boolean public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:614    callback Function The callback to execute target Object The target object to use returns Boolean `true` if the passed function returns `true` for any item  Returns true if the passed function returns true for any item in the enumeration. The callback method you provide should have the following signature (all parameters are optional): function(item, index, enumerable);  
item is the current item in the iteration. 
index is the current index in the iteration. 
enumerable is the enumerable object itself.  It must return a truthy value (i.e. true) to include an item in the results. Any non-truthy return value will discard the item from the results. Note that in addition to a callback, you can also pass an optional target object that will be set as this on the context. This is a good way to give your iterator function access to the current object. Usage Example: if (people.any(isManager)) {
  Paychecks.addBiggerBonus();
}  arrayContentDidChange  (startIdx, removeAmt, addAmt)  EmberArray public    Module: @ember/array    Inherited from  EmberArray packages/ember-runtime/lib/mixins/array.js:529    startIdx Number The starting index in the array that did change. removeAmt Number The number of items that were removed. If you pass `null` assumes 0 addAmt Number The number of items that were added. If you pass `null` assumes 0. returns EmberArray receiver  If you are implementing an object that supports EmberArray, call this method just after the array content changes to notify any observers and invalidate any related properties. Pass the starting index of the change as well as a delta of the amounts to change.  arrayContentWillChange  (startIdx, removeAmt, addAmt)  EmberArray public    Module: @ember/array    Inherited from  EmberArray packages/ember-runtime/lib/mixins/array.js:510    startIdx Number The starting index in the array that will change. removeAmt Number The number of items that will be removed. If you pass `null` assumes 0 addAmt Number The number of items that will be added. If you pass `null` assumes 0. returns EmberArray receiver  If you are implementing an object that supports EmberArray, call this method just before the array content changes to notify any observers and invalidate any related properties. Pass the starting index of the change as well as a delta of the amounts to change.  cacheFor  (keyName)  Object public    Module: @ember/array    Inherited from  Observable packages/ember-runtime/lib/mixins/observable.js:489    keyName String returns Object The cached value of the computed property, if any  Returns the cached value of a computed property, if it exists. This allows you to inspect the value of a computed property without accidentally invoking it if it is intended to be generated lazily.  clear Ember.Array public    Module: @ember/array    Inherited from  MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:79    returns Ember.Array An empty Array.  Remove all elements from the array. This is useful if you want to reuse an existing array without having to recreate it. let colors = ['red', 'green', 'blue'];

colors.length;  // 3
colors.clear(); // []
colors.length;  // 0  compact Array public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:778    returns Array the array without null and undefined elements.  Returns a copy of the array with all null and undefined elements removed. let arr = ['a', null, 'c', undefined];
arr.compact();  // ['a', 'c']  decrementProperty  (keyName, decrement)  Number public    Module: @ember/array    Inherited from  Observable packages/ember-runtime/lib/mixins/observable.js:452    keyName String The name of the property to decrement decrement Number The amount to decrement by. Defaults to 1 returns Number The new property value  Set the value of a property to the current value minus some amount. player.decrementProperty('lives');
orc.decrementProperty('health', 5);  destroy EmberObject public    Module: @ember/array    Inherited from  CoreObject packages/ember-runtime/lib/system/core_object.js:445    returns EmberObject receiver  Destroys an object by setting the isDestroyed flag and removing its metadata, which effectively destroys observers and bindings. If you try to set a property on a destroyed object, an exception will be raised. Note that destruction is scheduled for the end of the run loop and does not happen immediately. It will set an isDestroying flag immediately.  every  (callback, target)  Boolean public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:554    callback Function The callback to execute target Object The target object to use returns Boolean  Returns true if the passed function returns true for every item in the enumeration. This corresponds with the every() method in JavaScript 1.6. The callback method you provide should have the following signature (all parameters are optional): function(item, index, enumerable);  
item is the current item in the iteration. 
index is the current index in the iteration. 
enumerable is the enumerable object itself.  It should return the true or false. Note that in addition to a callback, you can also pass an optional target object that will be set as this on the context. This is a good way to give your iterator function access to the current object. Example Usage: if (people.every(isEngineer)) {
  Paychecks.addBigBonus();
}  filter  (callback, target)  Array public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:365    callback Function The callback to execute target Object The target object to use returns Array A filtered array.  Returns an array with all of the items in the enumeration that the passed function returns true for. This method corresponds to filter() defined in JavaScript 1.6. The callback method you provide should have the following signature (all parameters are optional): function(item, index, enumerable);  
item is the current item in the iteration. 
index is the current index in the iteration. 
enumerable is the enumerable object itself.  It should return true to include the item in the results, false otherwise. Note that in addition to a callback, you can also pass an optional target object that will be set as this on the context. This is a good way to give your iterator function access to the current object.  filterBy  (key, value)  Array public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:443    key String the property to test value * optional value to test against. returns Array filtered array  Returns an array with just the items with the matched property. You can pass an optional second argument with the target value. Otherwise this will match any property that evaluates to true.  find  (callback, target)  Object public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:477    callback Function The callback to execute target Object The target object to use returns Object Found item or `undefined`.  Returns the first item in the array for which the callback returns true. This method works similar to the filter() method defined in JavaScript 1.6 except that it will stop working on the array once a match is found. The callback method you provide should have the following signature (all parameters are optional): function(item, index, enumerable);  
item is the current item in the iteration. 
index is the current index in the iteration. 
enumerable is the enumerable object itself.  It should return the true to include the item in the results, false otherwise. Note that in addition to a callback, you can also pass an optional target object that will be set as this on the context. This is a good way to give your iterator function access to the current object.  findBy  (key, value)  Object public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:537    key String the property to test value String optional value to test against. returns Object found item or `undefined`  Returns the first item with a property matching the passed value. You can pass an optional second argument with the target value. Otherwise this will match any property that evaluates to true. This method works much like the more generic find() method.  forEach  (callback, target)  Object public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:240    callback Function The callback to execute target Object The target object to use returns Object receiver  Iterates through the enumerable, calling the passed function on each item. This method corresponds to the forEach() method defined in JavaScript 1.6. The callback method you provide should have the following signature (all parameters are optional): function(item, index, enumerable);  
item is the current item in the iteration. 
index is the current index in the iteration. 
enumerable is the enumerable object itself.  Note that in addition to a callback, you can also pass an optional target object that will be set as this on the context. This is a good way to give your iterator function access to the current object.  get  (keyName)  Object public    Module: @ember/array    Inherited from  Observable packages/ember-runtime/lib/mixins/observable.js:94    keyName String The property to retrieve returns Object The property value or undefined.  Retrieves the value of a property from the object. This method is usually similar to using object[keyName] or object.keyName, however it supports both computed properties and the unknownProperty handler. Because get unifies the syntax for accessing all these kinds of properties, it can make many refactorings easier, such as replacing a simple property with a computed property, or vice versa. Computed Properties Computed properties are methods defined with the property modifier declared at the end, such as: fullName: Ember.computed('firstName', 'lastName', function() {
  return this.get('firstName') + ' ' + this.get('lastName');
}) When you call get on a computed property, the function will be called and the return value will be returned instead of the function itself. Unknown Properties Likewise, if you try to call get on a property whose value is undefined, the unknownProperty() method will be called on the object. If this method returns any value other than undefined, it will be returned instead. This allows you to implement "virtual" properties that are not defined upfront.  getEach  (key)  Array public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:289    key String name of the property returns Array The mapped array.  Alias for mapBy  getProperties  (list)  Object public    Module: @ember/array    Inherited from  Observable packages/ember-runtime/lib/mixins/observable.js:137    list String...|Array of keys to get returns Object  To get the values of multiple properties at once, call getProperties with a list of strings or an array: record.getProperties('firstName', 'lastName', 'zipCode');
// { firstName: 'John', lastName: 'Doe', zipCode: '10011' } is equivalent to: record.getProperties(['firstName', 'lastName', 'zipCode']);
// { firstName: 'John', lastName: 'Doe', zipCode: '10011' }  getWithDefault  (keyName, defaultValue)  Object public    Module: @ember/array    Inherited from  Observable packages/ember-runtime/lib/mixins/observable.js:414    keyName String The name of the property to retrieve defaultValue Object The value to return if the property value is undefined returns Object The property value or the defaultValue.  Retrieves the value of a property, or a default value in the case that the property returns undefined. person.getWithDefault('lastName', 'Doe');  includes  (obj)  Boolean public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:1112    obj Object The object to search for. returns Boolean `true` if object is found in the enumerable.  Returns true if the passed object can be found in the enumerable. [1, 2, 3].includes(2);                     // true
[1, 2, 3].includes(4);                     // false
[1, 2, undefined].includes(undefined);     // true
[1, 2, null].includes(null);               // true
[1, 2, NaN].includes(NaN);                 // true  incrementProperty  (keyName, increment)  Number public    Module: @ember/array    Inherited from  Observable packages/ember-runtime/lib/mixins/observable.js:432    keyName String The name of the property to increment increment Number The amount to increment by. Defaults to 1 returns Number The new property value  Set the value of a property to the current value plus some amount. person.incrementProperty('age');
team.incrementProperty('score', 2);  indexOf  (object, startAt)  Number public    Module: @ember/array    Inherited from  EmberArray packages/ember-runtime/lib/mixins/array.js:363    object Object the item to search for startAt Number optional starting location to search, default 0 returns Number index or -1 if not found  Returns the index of the given object's first occurrence. If no startAt argument is given, the starting location to search is 0. If it's negative, will count backward from the end of the array. Returns -1 if no match is found. let arr = ['a', 'b', 'c', 'd', 'a'];

arr.indexOf('a');       //  0
arr.indexOf('z');       // -1
arr.indexOf('a', 2);    //  4
arr.indexOf('a', -1);   //  4
arr.indexOf('b', 3);    // -1
arr.indexOf('a', 100);  // -1  init public    Module: @ember/array    Inherited from  CoreObject packages/ember-runtime/lib/system/core_object.js:210   An overridable method called when objects are instantiated. By default, does nothing unless it is overridden during class definition. Example: const Person = Ember.Object.extend({
  init() {
    alert(`Name is ${this.get('name')}`);
  }
});

let steve = Person.create({
  name: 'Steve'
});

// alerts 'Name is Steve'. NOTE: If you do override init for a framework class like Ember.View, be sure to call this._super(...arguments) in your init declaration! If you don't, Ember may not have an opportunity to do important setup work, and you'll see strange behavior in your application.  insertAt  (idx, object)  EmberArray public    Module: @ember/array    Inherited from  MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:105    idx Number index of insert the object at. object Object object to insert returns EmberArray receiver  This will use the primitive replace() method to insert an object at the specified index. let colors = ['red', 'green', 'blue'];

colors.insertAt(2, 'yellow');  // ['red', 'green', 'yellow', 'blue']
colors.insertAt(5, 'orange');  // Error: Index out of range  invoke  (methodName, args)  Array public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:737    methodName String the name of the method args Object... optional arguments to pass as well. returns Array return values from calling invoke.  Invokes the named method on every object in the receiver that implements it. This method corresponds to the implementation in Prototype 1.6.  isAny  (key, value)  Boolean public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:675    Available since v1.3.0   key String the property to test value String optional value to test against. Defaults to `true` returns Boolean  Returns true if the passed property resolves to the value of the second argument for any item in the enumerable. This method is often simpler/faster than using a callback.  isEvery  (key, value)  Boolean public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:595    Available since v1.3.0   key String the property to test value String optional value to test against. Defaults to `true` returns Boolean  Returns true if the passed property resolves to the value of the second argument for all items in the enumerable. This method is often simpler/faster than using a callback. Note that like the native Array.every, isEvery will return true when called on any empty enumerable.  lastIndexOf  (object, startAt)  Number public    Module: @ember/array    Inherited from  EmberArray packages/ember-runtime/lib/mixins/array.js:406    object Object the item to search for startAt Number optional starting location to search, default 0 returns Number index or -1 if not found  Returns the index of the given object's last occurrence. If no startAt argument is given, the search starts from the last position. If it's negative, will count backward from the end of the array. Returns -1 if no match is found. let arr = ['a', 'b', 'c', 'd', 'a'];

arr.lastIndexOf('a');       //  4
arr.lastIndexOf('z');       // -1
arr.lastIndexOf('a', 2);    //  0
arr.lastIndexOf('a', -1);   //  4
arr.lastIndexOf('b', 3);    //  1
arr.lastIndexOf('a', 100);  //  4  map  (callback, target)  Array public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:315    callback Function The callback to execute target Object The target object to use returns Array The mapped array.  Maps all of the items in the enumeration to another value, returning a new array. This method corresponds to map() defined in JavaScript 1.6. The callback method you provide should have the following signature (all parameters are optional): function(item, index, enumerable);  
item is the current item in the iteration. 
index is the current index in the iteration. 
enumerable is the enumerable object itself.  It should return the mapped value. Note that in addition to a callback, you can also pass an optional target object that will be set as this on the context. This is a good way to give your iterator function access to the current object.  mapBy  (key)  Array public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:352    key String name of the property returns Array The mapped array.  Similar to map, this specialized function returns the value of the named property on all items in the enumeration.  notifyPropertyChange  (keyName)  Observable public    Module: @ember/array    Inherited from  Observable packages/ember-runtime/lib/mixins/observable.js:316    keyName String The property key to be notified about. returns Observable  Convenience method to call propertyWillChange and propertyDidChange in succession.  objectAt  (idx)  * public    Module: @ember/array    Inherited from  EmberArray packages/ember-runtime/lib/mixins/array.js:224    idx Number The index of the item to return. returns * item at index or undefined  Returns the object at the given index. If the given index is negative or is greater or equal than the array length, returns undefined. This is one of the primitives you must implement to support EmberArray. If your object supports retrieving the value of an array item using get() (i.e. myArray.get(0)), then you do not need to implement this method yourself. let arr = ['a', 'b', 'c', 'd'];

arr.objectAt(0);   // 'a'
arr.objectAt(3);   // 'd'
arr.objectAt(-1);  // undefined
arr.objectAt(4);   // undefined
arr.objectAt(5);   // undefined  objectAtContent  (idx)  Object public    Module: @ember/array    Defined in  packages/ember-runtime/lib/system/array_proxy.js:93    idx Number The index to retrieve. returns Object the value or undefined if none found  Should actually retrieve the object at the specified index from the content. You can override this method in subclasses to transform the content item to something new. This method will only be called if content is non-null.  objectsAt  (indexes)  Array public    Module: @ember/array    Inherited from  EmberArray packages/ember-runtime/lib/mixins/array.js:256    indexes Array An array of indexes of items to return. returns Array  This returns the objects at the specified indexes, using objectAt. let arr = ['a', 'b', 'c', 'd'];

arr.objectsAt([0, 1, 2]);  // ['a', 'b', 'c']
arr.objectsAt([2, 3, 4]);  // ['c', 'd', undefined]  popObject public    Module: @ember/array    Inherited from  MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:200    returns object  Pop object from array or nil if none are left. Works just like pop() but it is KVO-compliant. let colors = ['red', 'green', 'blue'];

colors.popObject();   // 'blue'
console.log(colors);  // ['red', 'green']  pushObject  (obj)  public    Module: @ember/array    Inherited from  MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:156    obj * object to push returns object same object passed as a param  Push the object onto the end of the array. Works just like push() but it is KVO-compliant. let colors = ['red', 'green'];

colors.pushObject('black');     // ['red', 'green', 'black']
colors.pushObject(['yellow']);  // ['red', 'green', ['yellow']]  pushObjects  (objects)  EmberArray public    Module: @ember/array    Inherited from  MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:177    objects Enumerable the objects to add returns EmberArray receiver  Add the objects in the passed numerable to the end of the array. Defers notifying observers of the change until all objects are added. let colors = ['red'];

colors.pushObjects(['yellow', 'orange']);  // ['red', 'yellow', 'orange']  reduce  (callback, initialValue, reducerProperty)  Object public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:691    callback Function The callback to execute initialValue Object Initial value for the reduce reducerProperty String internal use only. returns Object The reduced value.  This will combine the values of the enumerator into a single value. It is a useful way to collect a summary value from an enumeration. This corresponds to the reduce() method defined in JavaScript 1.8. The callback method you provide should have the following signature (all parameters are optional): function(previousValue, item, index, enumerable);  
previousValue is the value returned by the last call to the iterator. 
item is the current item in the iteration. 
index is the current index in the iteration. 
enumerable is the enumerable object itself.  Return the new cumulative value. In addition to the callback you can also pass an initialValue. An error will be raised if you do not pass an initial value and the enumerator is empty. Note that unlike the other methods, this method does not allow you to pass a target object to set as this for the callback. It's part of the spec. Sorry.  reject  (callback, target)  Array public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:408    callback Function The callback to execute target Object The target object to use returns Array A rejected array.  Returns an array with all of the items in the enumeration where the passed function returns false. This method is the inverse of filter(). The callback method you provide should have the following signature (all parameters are optional): function(item, index, enumerable);  
item is the current item in the iteration. 
index is the current index in the iteration 
enumerable is the enumerable object itself.  It should return a falsey value to include the item in the results. Note that in addition to a callback, you can also pass an optional target object that will be set as "this" on the context. This is a good way to give your iterator function access to the current object.  rejectBy  (key, value)  Array public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:458    key String the property to test value String optional value to test against. returns Array rejected array  Returns an array with the items that do not have truthy values for key. You can pass an optional second argument with the target value. Otherwise this will match any property that evaluates to false.  removeArrayObserver  (target, opts)  EmberArray public    Module: @ember/array    Inherited from  EmberArray packages/ember-runtime/lib/mixins/array.js:483    target Object The object observing the array. opts Object Optional hash of configuration options including `willChange` and `didChange` option. returns EmberArray receiver  Removes an array observer from the object if the observer is current registered. Calling this method multiple times with the same object will have no effect.  removeAt  (start, len)  EmberArray public    Module: @ember/array    Inherited from  MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:131    start Number index, start of range len Number length of passing range returns EmberArray receiver  Remove an object at the specified index using the replace() primitive method. You can pass either a single index, or a start and a length. If you pass a start and length that is beyond the length this method will throw an OUT_OF_RANGE_EXCEPTION. let colors = ['red', 'green', 'blue', 'yellow', 'orange'];

colors.removeAt(0);     // ['green', 'blue', 'yellow', 'orange']
colors.removeAt(2, 2);  // ['green', 'blue']
colors.removeAt(4, 2);  // Error: Index out of range  removeObject  (object)  Object public    Module: @ember/array    Inherited from  Ember.MutableEnumerable packages/ember-runtime/lib/mixins/mutable_enumerable.js:86    object Object The object to remove from the enumerable. returns Object the passed object  Required. You must implement this method to apply this mixin. Attempts to remove the passed object from the receiver collection if the object is present in the collection. If the object is not present, this method has no effect. If the passed object is of a type not supported by the receiver, then this method should raise an exception.  removeObjects  (objects)  Object public    Module: @ember/array    Inherited from  Ember.MutableEnumerable packages/ember-runtime/lib/mixins/mutable_enumerable.js:104    objects Ember.Enumerable the objects to remove returns Object receiver  Removes each object in the passed enumerable from the receiver.  removeObserver  (key, target, method)  Ember.Observable public    Module: @ember/array    Inherited from  Observable packages/ember-runtime/lib/mixins/observable.js:382    key String The key to observe target Object The target object to invoke method String|Function The method to invoke returns Ember.Observable  Remove an observer you have previously registered on this object. Pass the same key, target, and method you passed to addObserver() and your target will no longer receive notifications.  replace  (idx, amt, objects)  public    Module: @ember/array    Inherited from  MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:61    idx Number Starting index in the array to replace. If idx >= length, then append to the end of the array. amt Number Number of elements that should be removed from the array, starting at *idx*. objects EmberArray An array of zero or more objects that should be inserted into the array at *idx*  Required. You must implement this method to apply this mixin. This is one of the primitives you must implement to support Ember.Array. You should replace amt objects started at idx with the objects in the passed array. You should also call this.enumerableContentDidChange()  reverseObjects EmberArray public    Module: @ember/array    Inherited from  MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:293    returns EmberArray receiver  Reverse objects in the array. Works just like reverse() but it is KVO-compliant.  set  (keyName, value)  Object public    Module: @ember/array    Inherited from  Observable packages/ember-runtime/lib/mixins/observable.js:162    keyName String The property to set value Object The value to set or `null`. returns Object The passed value  Sets the provided key or path to the value. record.set("key", value); This method is generally very similar to calling object["key"] = value or object.key = value, except that it provides support for computed properties, the setUnknownProperty() method and property observers. Computed Properties If you try to set a value on a key that has a computed property handler defined (see the get() method for an example), then set() will call that method, passing both the value and key instead of simply changing the value itself. This is useful for those times when you need to implement a property that is composed of one or more member properties. Unknown Properties If you try to set a value on a key that is undefined in the target object, then the setUnknownProperty() handler will be called instead. This gives you an opportunity to implement complex "virtual" properties that are not predefined on the object. If setUnknownProperty() returns undefined, then set() will simply set the value on the object. Property Observers In addition to changing the property, set() will also register a property change with the object. Unless you have placed this call inside of a beginPropertyChanges() and endPropertyChanges(), any "local" observers (i.e. observer methods declared on the same object), will be called immediately. Any "remote" observers (i.e. observer methods declared on another object) will be placed in a queue and called at a later time in a coalesced manner.  setEach  (key, value)  Object public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:299    key String The key to set value Object The object to set returns Object receiver  Sets the value on the named property for each member. This is more ergonomic than using other methods defined on this helper. If the object implements Ember.Observable, the value will be changed to set(), otherwise it will be set directly. null objects are skipped.  setObjects  (objects)  EmberArray public    Module: @ember/array    Inherited from  MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:312    objects EmberArray array whose content will be used for replacing the content of the receiver returns EmberArray receiver with the new content  Replace all the receiver's content with content of the argument. If argument is an empty array receiver will be cleared. let colors = ['red', 'green', 'blue'];

colors.setObjects(['black', 'white']);  // ['black', 'white']
colors.setObjects([]);                  // []  setProperties  (hash)  Object public    Module: @ember/array    Inherited from  Observable packages/ember-runtime/lib/mixins/observable.js:211    hash Object the hash of keys and values to set returns Object The passed in hash  Sets a list of ronaldfernandez@example.org. These properties are set inside a single beginPropertyChanges and endPropertyChanges batch, so observers will be buffered. record.setProperties({ firstName: 'Charles', lastName: 'Jolley' });  shiftObject public    Module: @ember/array    Inherited from  MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:226    returns object  Shift an object from start of array or nil if none are left. Works just like shift() but it is KVO-compliant. let colors = ['red', 'green', 'blue'];

colors.shiftObject();  // 'red'
console.log(colors);   // ['green', 'blue']  slice  (beginIndex, endIndex)  Array public    Module: @ember/array    Inherited from  EmberArray packages/ember-runtime/lib/mixins/array.js:321    beginIndex Number (Optional) index to begin slicing from. endIndex Number (Optional) index to end the slice at (but not included). returns Array New array with specified slice  Returns a new array that is a slice of the receiver. This implementation uses the observable array methods to retrieve the objects for the new slice. let arr = ['red', 'green', 'blue'];

arr.slice(0);       // ['red', 'green', 'blue']
arr.slice(0, 2);    // ['red', 'green']
arr.slice(1, 100);  // ['green', 'blue']  sortBy  (property)  Array public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:1052    Available since v1.2.0   property String name(s) to sort on returns Array The sorted array.  Converts the enumerable into an array and sorts by the keys specified in the argument. You may provide multiple arguments to sort by multiple properties.  toArray Array public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:762    returns Array the enumerable as an array.  Simply converts the enumerable into a genuine array. The order is not guaranteed. Corresponds to the method implemented by Prototype.  toString String public    Module: @ember/array    Inherited from  CoreObject packages/ember-runtime/lib/system/core_object.js:498    returns String string representation  Returns a string representation which attempts to provide more information than Javascript's toString typically does, in a generic way for all Ember objects. const Person = Ember.Object.extend()
person = Person.create()
person.toString() //=> "<Person:ember1024>" If the object's class is not defined on an Ember namespace, it will indicate it is a subclass of the registered superclass: const Student = Person.extend()
let student = Student.create()
student.toString() //=> "<(subclass of Person):ember1025>" If the method toStringExtension is defined, its return value will be included in the output. const Teacher = Person.extend({
  toStringExtension() {
    return this.get('fullName');
  }
});
teacher = Teacher.create()
teacher.toString(); //=> "<Teacher:ember1026:Tom Dale>"  toggleProperty  (keyName)  Boolean public    Module: @ember/array    Inherited from  Observable packages/ember-runtime/lib/mixins/observable.js:472    keyName String The name of the property to toggle returns Boolean The new property value  Set the value of a boolean property to the opposite of its current value. starship.toggleProperty('warpDriveEngaged');  uniq Ember.Enumerable public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:826    returns Ember.Enumerable  Returns a new enumerable that contains only unique values. The default implementation returns an array regardless of the receiver type. let arr = ['a', 'a', 'b', 'b'];
arr.uniq();  // ['a', 'b'] This only works on primitive data types, e.g. Strings, Numbers, etc.  uniqBy Ember.Enumerable public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:1083    returns Ember.Enumerable  Returns a new enumerable that contains only items containing a unique property value. The default implementation returns an array regardless of the receiver type. let arr = [{ value: 'a' }, { value: 'a' }, { value: 'b' }, { value: 'b' }];
arr.uniqBy('value');  // [{ value: 'a' }, { value: 'b' }]  unshiftObject  (obj)  public    Module: @ember/array    Inherited from  MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:251    obj * object to unshift returns object same object passed as a param  Unshift an object to start of array. Works just like unshift() but it is KVO-compliant. let colors = ['red'];

colors.unshiftObject('yellow');    // ['yellow', 'red']
colors.unshiftObject(['black']);   // [['black'], 'yellow', 'red']  unshiftObjects  (objects)  EmberArray public    Module: @ember/array    Inherited from  MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:272    objects Enumberable the objects to add returns EmberArray receiver  Adds the named objects to the beginning of the array. Defers notifying observers until all objects have been added. let colors = ['red'];

colors.unshiftObjects(['black', 'white']);   // ['black', 'white', 'red']
colors.unshiftObjects('yellow'); // Type Error: 'undefined' is not a function  willDestroy public    Module: @ember/array    Inherited from  CoreObject packages/ember-runtime/lib/system/core_object.js:471   Override to implement teardown.  without  (value)  Ember.Enumerable public    Module: @ember/array    Inherited from  Enumerable packages/ember-runtime/lib/mixins/enumerable.js:794    value Object returns Ember.Enumerable  Returns a new enumerable that excludes the passed value. The default implementation returns an array regardless of the receiver type. If the receiver does not contain the value it returns the original enumerable. let arr = ['a', 'b', 'a', 'c'];
arr.without('a');  // ['b', 'c']
