I had the same opinion with async/await, that it's nice to know a function performs IO and will wait before continuing. Makes it clearer when to use Promise.all to make multiple requests in parallel and wait for all of them to finish before continuing (faster than making calls sequentially).
I kind of wish the languages I use had Haskell's IO monad too, to separate functions in terms of the type system, but that's slightly different.
