cara menelepon menunggu fungsi async di js

// You can't use await outside an async function. one trick to 'bypass' this limit is to use async IFEE:
const myAsyncFunction = async() => {
    return await getValue()
};

// Bypass it as follows:
let value;
(async () => {
    value = await myAsyncFunction()
})()
