Ember.js is a JavaScript framework for creating ambitious web applications by eliminating boilerplate and providing a standard application architecture.

Ember.js, like some other modern JavaScript frameworks, works a little differently. Instead of the majority of your application’s logic living on the server, an Ember.js application downloads everything it needs to run in the initial page load. That means that while your user is using your app, she never has to load a new page and your UI responds quickly to their interaction.

One advantage of this architecture is that your web application uses the same REST API as your native apps or third-party clients. Back-end developers can focus on building a fast, reliable, and secure API server, and don’t have to be front-end experts, too.
