Every language pitches async/await as synchronous-looking code, and the same two keywords appear everywhere. But behind the shared syntax hide nine independent design decisions, and no two of seven modern runtimes agree on what even the simplest async programs should do! In this paper we map the design space of async/await so you can find out where your language stands.
Personally, I hate awaiting async actions and prefer callbacks. Just execute when done, thanks. I don’t care in which order.
Same I still prefer promises in JavaScript over async await for this reason.
