js异步数据从json到数组

Question

如何使用异步获取 JSON 数据并将它们发送到变量或以任何方式处理它们？实在是无法理解这一点。

let FormEntries=[];
    
async function getUserAsync(){
let response = await fetch(`myremotejson`);
let data = await response.json()
return data;
}

function processData(data){
console.log(data) //returns 'undefined', 'cause data didn't come to function?
FormEntries = data; //does nothing, 'cause data didn't come to function?
}


getUserAsync()
  .then(data => console.log(data)) //returns data - OK
  .then(data => processData(data)) //I want to send these data to my FormEntries array, HOW?

试试这个

const getUserAsync = async () => {
let response = await fetch(`myremotejson`);
let data = await response.json();
 processData(data);
};

function processData(data) {
console.log(data) ;
FormEntries = data; 
};

getUserAsync();
