this is my javascript code. I want to know how to receive data as a global variable. (bbbbb is successd, but aaaaa is not sucessed)

Answer 1

let globalData;
async function getData()
{
    let response = await fetch('http://~~~');
    globalData = response.yourData;
}

getData(); 
// even you dont need this thing to do. 
// getData().then(data => console.log("bbbbb",data));

console.log("aaaaa", globalData);

By this, globalData variable is global now. and you can get data by globalData .

Answer 2

let data;
async function getData()
{
    let response = await fetch('http://~~~');
    data = await response.json();
    return data;
}

getData()

console.log("aaaaa",data);

Anything outside you function scope can be considered as global. Here data is a global variable
