What are enumerable in ember.js?

An enumerable is any object in ember.js which contains a number of child objects and allows us to work with those children using “ember.enumerable” API. The native JavaScript array is the most common enumerable in a majority of applications, which ember.js extends to conform to the enumerable interface. Ember.js provides us with a standardized interface for dealing with the enumerable and allows us to completely change the way our underlying data is stored without modifying the other parts of the application which accesses it. This API follows ECMAScript specifications as much as possible which hence minimizes the incompatibility with other libraries. It also allows ember.js to use the native browser implementations in arrays where they are available.
