1: async 异步回调 (ES6)
async function test(){
       console.log("hello wolrd");
 }
 test().then(function(){
     console.log("回调测试")
 }); 
2: 沉睡排序
var numbers=[1,2,3,4,5,5,99,4,20,11,200];
numbers.forEach((num)=>{
    setTimeout(()=>{
        console.log(num)
    },num)
})
3: 快速去重 (ES6)
var arr = Array.from(new Set([1,2,3,4,4,3,5,6,7,8,8]));
还在不断收集更新中........
