CommonJs and AMD
1：the first difference is async 。the CommonJs begin to exec the code when the source loaded at the same time！eg: var a = require('./a');console.log('a',a)。However，AMD rules begin to exec the code when the source loaded ！eg: define(require,module,expore){ }
2：the CommonJs is fit for Nodejs ,as the scoure is in the local disck ，But the AMD is suit to Explore Project ,just like Html5 。（seajs is AMD ）
3：require supply the main、cache、extensions、resolve ，it also can anysc exec function by ensure。
