05.module.js

var hello = require("./helloModule");

/*
	exports 和 module.exports
		- 通过exports只能使用.的方式来向外暴露内部变量
			exports.xxx = xxx

		- 而module.exports既可以通过.的形式，也可以直接赋值
			module.exports.xxx = xxxx
			module.exports = {}
 */

console.log(hello.name);
console.log(hello.age);
hello.sayName();

helloModule.js

/*
module.exports.name = "孙悟空";
module.exports.age = 18;
module.exports.sayName = function () {
	console.log("我是孙悟空~~~");
};*/

//exports = module.exports

/*exports  = {
	name:"猪八戒",
	age:28,
	sayName:function () {
		console.log("我是猪八戒");
	}
};*/

/*var a = 10;
var b = a;
a++;*/

// console.log("a = "+a);
// console.log("b = "+b);

/*var obj = new Object();
obj.name = "孙悟空";
var obj2 = obj;
obj2.name = "猪八戒";
