Ember是一个雄心勃勃的Web应用程序，消除了样板，并提供了一个标准的应用程序架构的JavaScript框架。

Ember.js 1.0 RC3 发布了，比起 RC2 版本，RC3 在性能又进一步提升，同时还包含如下改进：

• When adjacent child views are scheduled for insertion they are are now batched together, and inserted together rather then one at a time.
• Object deletion is now async, this prevents un-needed churn when destroying large interconnected object graphs.
• The number of objects allocated during view rendering has been cut down.

示例代码：

01	MyApp.president = Ember.Object.create({

02	firstName: "Barack",

03	lastName: "Obama",

04

05	fullName: function() {

06	return this.get('firstName') + ' ' + this.get('lastName');

07

08	// Tell Ember that this computed property depends on firstName

09	// and lastName

10	}.property('firstName', 'lastName')

11

});
