Amd,cmd,common.js and ES6 Simple comparison

AMD is the normalized output of the module defined by Require.js in the promotion process.

1. Relying on the predecessor

function　　(Alpha) {  returnfunction() {  return alpha.verb () + 2; 　　}　　}; });

Define (function(require, exports) {  //  get module A's interface  var a = require ('./a ')  ; // method of calling module a   a.dosomething ();});

Module.exports

module.exportsproperty represents the external output interface of the current module, and the other file loads the module, actually reading the module.exports variable.

ES6
