我有尝试过直接在浏览器环境下import一个js文件,结果是报错
SyntaxError: Unexpected token import
, 这个需要在node环境里使用babel工具将其转化为ES5代码,这个可以在babel官网体验babel官网
这里做了一个测试
// 使用ES6的import写法
import {sex,echo} from "./a.js"
console.log(sex) // boy
echo(sex) // boy
//经过babel转变之后
"use strict";
var _a = require("./a.js");
console.log(_a.sex); // boy
(0, _a.echo)(_a.sex); // boy

require是node遵循ommonJS模块规范,内置的命名,用来加载模块文件
-
require命令的基本功能是,读入并执行一个JavaScript文件,然后返回该模块的exports对象。如果没有发现指定模块,会报错
