CommonJS根据JS的表现制定规范： {模块引用(require)} {模块定义(exports)} {模块标识(module)} NodeJS遵循了CommonJS规范，写法如下： 12345// foo.jsmodule.exports = function(x) { console.log(x);}; 1234// index.jslet foo = require('./foo')foo(1); CommonJS主要为了JS在后端制定的规范，但并不适用与前端，因为代码在是通过网络加载，所以AMD（异步模块定义）出现： define([‘dep1’,’dep2’],function(dep1,dep2){…}); RequireJS实现了AMD规范，写法如下： 1234567// foo.jsdefine(function() { return function(x) { console.log(x); };}); 12345// ind ...

The original link Hi folks, As a front end developers we need to deal with different data models which come from the server side. We have to format them , change them and yes! we need to validate them. Mainly JSON at these days. In most cases back end data not in the way it should be.(Back end developers doesn’t bother to format data that much).Hence we are in a dark when we are going to render that data in our view. If you are angularjs user, Hell! you are in the business. Fortunately angularjs ...
