The rise of async AI programming

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.

Man are you going to be disappointed when you read the article.

To elaborate a bit, telling them that you should not "aList.foreach(asyncMethod)", but you'd better do "Promise.all(aList.map(asyncMethod))" is NOT very easy for them.

Man, for the first time in HN, I am teased to actually read the article.

Update: oh my god, I read the article. And feel completely cheated!!!!

Note for my future self: continue to read only the HN comments

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".

During my interviews, may be I should ask them to read and understand this:

prior to any dev they plan to do in JS/TS.

PS: 10 bucks that none of them would stay.
