“There are some tasks that are common to every web application. For example, taking data from the server, rendering it to the screen, then updating that information when it changes.
“Since the tools provided to do this by the browser are quite primitive, you end up writing the same code over and over. Ember.js provides tools that let you focus on your app instead of writing the same code you’ve written a hundred times.
“Because we’ve built dozens of applications ourselves, we’ve gone beyond the obvious low-level event-driven abstractions, eliminating much of the boilerplate associated with propagating changes throughout your application, and especially into the DOM itself.
“To help manage changes in the view, Ember.js comes with a templating engine that will automatically update the DOM when the underlying objects change.”
