JavaScript didn’t not have any async or parallelization keywords at all. Essentially it’s just passing a delegate that is called later. This was stabdardized into Promises and all the async/await is another wrapper around the promises.
It works well, because in the end, it’s just passing a function that should be called when the process finished.
