Javascript Get Result Of Async Function. The keyword await makes JavaScript wait until that promise settles and returns its result. GetData is a promise getDatathenres consolelogrescatcherr consolelogerr.
We need to call async wait and wait to get 10 remember we cant use await PS. Async function foo await wait500. Const mainFunction const result asynchronousFunction return result but asynchronousFunction performs some asynchronous call in it for example a fetch call and cant directly return the result value.
An asynchronous function is a function which operates asynchronously via the event loop using an implicit Promise to return its result.
Say we wanted to stream a response while logging out the chunks and return the final size. The await keyword tells JavaScript to wait until the promise from the asynchronous function is settled before executing the rest of the code. Say we wanted to stream a response while logging out the chunks and return the final size. The task is technically very simple but the question is quite common for developers new to asyncawait.
