(es6学习笔记05)class类的使用和模块化操作

class Coder {
    name(val){
        console.log(val);
        return val;
    }
    add(){
        return this.a+this.b;
    }
    constructor(a,b){//类的传参
        this.a=a;
        this.b=b;
    }
    
}
let jsp=new Coder(1,2);
console.log(jsp.add());
jsp.name(‘jspang‘);
//类的继承（我的理解是把Coder复制了一边，粘贴到了htmler上边）
class htmler extends Coder{
    adds(val) {
        console.log(val)
    }
}
let pang=new htmler;
pang.name(‘技术胖‘);
pang.adds(‘haha ‘);

var a =‘jspang‘;
var b =‘技术胖‘;
var c = ‘web‘;
export {
    a as x,
    b as y,
    c as z
}
//用的时候引入xyz就好了
