Backbone.js vs Ember.js: What are the differences?

What is Backbone.js? Give your JS App some Backbone with Models, Views, Collections, and Events. Backbone supplies structure to JavaScript-heavy applications by providing models key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing application over a RESTful JSON interface.

What is Ember.js? A JavaScript framework for creating ambitious web apps. Ember.js is a JavaScript framework that does all of the heavy lifting that you'd normally have to do by hand. There are tasks that are common to every web app; Ember.js does those things for you, so you can focus on building killer features and UI.

Backbone.js and Ember.js can be primarily classified as "Javascript MVC Frameworks" tools.
