What do you mean? In my experience, the use of async/await leads to much cleaner code for I/O driven tasks like querying APIs and databases. Yes, I do have a try/catch at the top of the callstack to catch and log unexpected errors.

async/await worries me, not for abstract language reasons but because it hides complexity in a way not friendly for junior engineers.

I imagine a lot of code that should be thought out and made parallel being forced into a synchronous flow.

Note that promises aren't a ton better in this regard, and come with a ton of confusion themselves. In short, async is hard.

Promise.all() does a pretty good job of parallelizing tasks while maintaining readability.
