Class is a template or blue print, that has a collection of variables and functions, whereas instances are related to the object of that class. You can create new Ember class by using the Ember.Object’s extend() method.

This is nothing but updating the class implementation without redefining it.

A computed property declares functions as properties and Ember.js automatically calls the computed properties when needed and combines one or more properties in one variable.

The computed property accesses all items in an array to determine its value.

The observer observes the property such as computed properties and updates the text of the computed property.

The binding is a powerful feature of Ember.js which helps to create a link between two properties and if one of the properties gets changed, the other one is updated automatically.
