require和import区别

使用形式不一样

const fs = require('fs');
 exports.fs = fs;
 module.exports = fs;

import

import fs from 'fs';
import {default as fs} from 'fs';
import * as fs from 'fs';
-----------------------------
export default fs;
export const fs;
export * from 'fs';

还有一个重要的区别
import是解析时候加载的，require是运行时加载，
require / exports 是 CommonJS(在Node中实现) , import / export 是 ES2015 的模块
