Understanding Ember.Object. Almost every object in Ember.js is derived from a common object: Ember.Object.
This object is used as the basis for views, controllers, models, and even the application itself. This simple architectural decision is responsible for much of the consistency across Ember. Because every object has been derived from the same core object, they all share some core capabilities. Every Ember object can observe the properties of other objects, bind their properties to the properties of other objects, specify and update computed properties, and much more. As you'll see in this post, it's easy to get started with Ember.Object, but also easy to overlook some of its capabilities.

Luke Melia » Using Ember.js with jQuery UI. Note: This post is a refresh of Yehuda Katz’s post of June 11, 2011, Using SproutCore 2.0 with jQuery UI.
Thanks to Yehuda for his review. Newest 'ember.js' Questions. Ember fiddle. Learn.Ember.js. This is an early prototype containing just the first page of a planned interactive tutorial on Ember.js, a JavaScript framework for building ambitious web applications.
For more details about the ongoing development of this tutorial, see this blog post. Unfortunately, this tutorial application does not work in Internet Explorer (yet). In this tutorial you'll explore the basics of building a web application using Ember's declarative bindings and MVC-friendly features. You'll learn how to define your UI's appearance using client-side HTML templates; how to define model, view, and controller objects using Ember's prototype-friendly class system; and how to use property accessors and declarative bindings to keep everything neatly synchronized. In the upper right pane is the Javascript code of a complete, if simple, Ember application that describes the name of a person. Click to see what this code does. (Code not working? As you can see, it just lists the first and last names as "TODO".
