// 类要领
foo.SayHi=function(){

// 原型要领

}

//测试
var xiaoming= new foo("xiaoming");
xiaoming.GetName();// 实例要领只能实例挪用，，内部要领只能被内部的要领挪用
foo.SayHi();//静态要领只能被类挪用
xiaoming.SayBye();//原型要领只能被实例挪用

静态要领

class Example{ static sum(a, b) { console.log(a+b); } }                             Example.sum(1, 2); // 3

原型要领

class Example { sum(a, b) { console.log(a + b); } }                                   let exam = new Example(); exam.sum(1, 2); // 3

实例要领

class Example { constructor() { this.sum = (a, b) => { console.log(a + b); } } }
