I am teaching asynchronous programming in typescript to junior developpers. And i find really tricky to tell them that async and await do MAJOR magic behind their back to make their code readable as synchronous code.

And then, I need to detail very precisely what "Promise.all()" (and "return") really mean in the context of async/await. Which is something that (I feel) could have been abstracted away during the async/await syntax definition, and make the full magic much more natural.

Async/await themselves are not that much magic really, it's a bit of syntactic sugar over promise chains. Of course, understanding promises is its own bag.

That reminds me of my Unix guru of the 90s: "man pages ARE easy to read".
