Ember.isArray()

Returns true if the passed object is an array or Array-like.

Objects are considered Array-like if any of the following are true:

• the object is a native Array
• the object has an objectAt property
• the object is an Object, and has a length property

Unlike Ember.typeOf this method returns true even if the passed object is not formally an array but appears to be array-like (i.e. implements Ember.Array)

Ember.isArray();                                          // false
Ember.isArray([]);                                        // true
Ember.isArray(Ember.ArrayProxy.create({ content: [] }));  // true
