AMD、CMD、ES6模块化规范

// 1、闭包立即执行函数
var module = (function(){
    var name = 'xiaoming';
    var print = () => console.log(name)
    return { print: print};
})();
module.print();

// 2、AMD规范(保存为math.js)
define(function (){
    var add = (x,y) => x+y
    return {add: add};
});
// 引用(需要require.js)
require(['math'], (math) => console(math.add(3, 4)))

// 3、CMD规范(保存为math.js)
var square = (x) => x * x
var diag = (x, y) => Math.sqrt(square(x) + square(y))
exports.square = square;
exports.diag = diag;
// 引用
var math = require("./math.js");
console.log(math.square(5));
console.log(math.diag(3, 4));

// 4、ES6规范(保存为module.js)
export default function fn1(msg) { //方式1
    console.log(msg)
}
export function fn2(msg) { //方式2
    console.log(msg)
}
function fn3(msg) { //方式3
    console.log(msg)
}
export {fn3}

// 默认导入(只可以导入一个方法)
import fn1 from './module.js'
fn1('fn1')
// 按需导入
import {fn2,fn3} from './module.js'
fn2('fn2')
fn3('fn3')
// 全部导入
import * as fn from './module.js'
fn.fn2('fn.fn2')
fn.fn3('fn.fn3')
