js循环中调用异步的方法，如何确保执行结果的顺序是正确的？

An example:

let searchApi = function(arg){    return new Promise((resolve,reject)=>{        setTimeout(()=>{ console.log(arg) resolve(arg)        }, 20)    })};let fields = [1,2,3,4];let arr = new Array(fields.length);await fields.forEach(async (vvv, index) => {    const obj = await searchApi(vvv)    arr[index] = obj    const tempArr = JSON.parse(JSON.stringify(arr))    if(tempArr.every(Boolean)){        console.log(arr)    }})
