`for await` is for async iterables, which is different. The loop body will still block the loop. Compare it to the all/map example I wrote.

True, it is sequential and not parallel. I think this syntax with an async generator could be made to do what you seek.

Async iterables are async generators. They call .next() on the iterable, that returns a promise, the promise resolves with either a new item to loop with, or with `done`, which will stop the loop.
