1. JS2 JS2 = JavaScript*JeffSu

7. JS2 类定义语法 class MyClass { var member1 = "member1”; function method1 () { alert("method1 called"); } }

10. 糅合（ Mixins ） module Flyable { function fly () { alert('Flying!'); } } class Bird { include Flyable; } class Duck { include Flyable; }

11. 静态方法 用于解决类似于唯一实例等问题 class Human { static function getCount () { return this.count; } static function create () { if (this.count) { this.count++; } else { this.count = 1; } return new this(); } }

14. HTML Cache //--- in uiBuilder.js2.haml UIBuilder button(name) %div.button= &quot;#name#&quot; //--- in uiBuilder.js2 class UIBuilder { function getButton (name) { this.htmlCache.button(name); } } //-- in uiBuilder.js UIBuilder.prototype = { htmlCache: {&quot;button&quot;: function(name){return &quot;<div class='button'>&quot;+name+&quot;</div>&quot;}} };
