Hot

``` Promise.retry=function(fn,number=3){ return function(...args){ let time=0; var next=function(resolve,reject){ fn(...args) .then(function(...res){ console.log(res) resolve(...res) }) .catch(function(...error){ if(time===number){ reject(...error); time=0; }else{ time++; next(resolve,reject) } }) } return new Promise(function(resolve,reject){ next(resolve,reject) }) } }...

``` function test() { async function next(list,index=0){ if(index===list.length)return; const res = await square(list[index]) next(list,index+1) } next(list) } ```

同样的问题,解决了么

必须在html中引用么,有没有其他办法

str.length?
