ES模块化导入和导出

    //1.导入的{}中定义的变量
    import{flag,sum} from"./asd.js";    //在asd.js中定义 flag 和 sum
    
    if(flag){
        console.log('Im gentle')
        console.log(sum(1,2));
    }
    
    //2.间接导入export定义的变量
    import {num1,height} from"./dfg.js
    
    console.log(num1);
    console.log(height);
    
    //3.导入export的function/class
    import {mul,person} from"./jkl.js";
    
    console.log(mul(10,20));
    
    const p = new person();
    p.run()
    
    //4.导入export default 中的内容
    import addr from ".oiu.js";
    
    addr('hello')
    
    //5.对立全副导入
    import * as qwe from './qwe.js'
    
    console.log(qwe.flag);
    console.log(qwe.height)
