一句话说清exports和module.exports的区别
无需多言,不明白这两者区别的大多没看官方解释,只有一句话 If you want the root of your module’s export to be a function (such as a constructor) or if you want to export a complete object in one assignment instead of building it one property at a time, assign it to module.exports instead of exports.
大家明白了吧

//个人理解 //node.js 默认声明 //var exports = {}; //module.exports = exports;
moudle.exports = {a:1}; exports.a = 2;
//导出的是{a:1}
var module = {
exports: {}
};
function your_module_define(require, exports, module){
//修改入参的引用, 不会影响外部变量
exports = {
nouse: null
};
//修改对象的引用才有用
module.exports = {}
}
