node 的exports 和module

文件05
/**
 * Created by Mr.tiankong on 2017/3/24.
 */
var People = require("./test/people.js");

var xiaoming = new People("小明","男","12");

xiaoming.sayHello();

文件People

/**
 * Created by Mr.tiankong on 2017/3/25.
 */
function People(name,sex,age)
{
    this.name = name;
    this.sex  = sex;
    this.age  = age;
}
People.prototype =
{
    sayHello:function()
    {
        console.log("这是模块儿里的"+this.name + this.sex + this.age);
    }
}
//不能用 exports.People = Peole 了 这是 规矩 有语法
//应该用 module 来暴露 功能是一样的 只是 方法不同
module.exports = People;

文件foo

/**
 * Created by Mr.tiankong on 2017/3/25.
 */
var msg="你好";
var info = "呵呵";
function  showInfo(){
 console.log("闭包");
}

//必须暴露这个对象 可以暴露无数变量
exports.msg = msg;
exports.info = info;
exports.
