- The function after
await someFunc()
need to return a promise. Otherwise it will not await and exit from the function. The function below will simply exit and won't wait till the background process is finished. Since async functions are waiting for Promises. The keyword await makes JavaScript wait until that promise settles and returns its result.
const hello4 = () => setTimeout(() => console.log('Hello from Hello4'), 5000)
const asycFunc = async() => {
await hello4()
return
}
