AngularJS ?诞生于2009年，由Misko Hevery 等人创建，后为Google所收购。是一款优秀的前端JS框架，已经被用于Google的多款产品当中。
AngularJS四大特征
1：MVC 模式
- Model:数据,其实就是angular变量($scope.XX);
- View: 数据的呈现,Html+Directive(指令);
- Controller:操作数据,就是function,数据的增删改查;
2：双向绑定
3：依赖注入
依赖注入(Dependency Injection,简称DI)是一种设计模式, 指某个对象依赖的其他对象无需手工创建，只需要“吼一嗓子”，则此对象在创建时，其依赖的对象由框架来自动创建并注入进来,其实就是最少知识法则。
4：模块化设计
高内聚低耦合法则
1)官方提供的模块：ng、ngRoute（路由）、ngAnimate（动画）
2)用户自定义的模块：angular.module(‘模块名‘,[ ])
