It's syntactic sugar that makes code a lot easier to reason about.

  Synchronous code is even easier to reason about than code using async syntax sugar.

    No, multithreaded synchronous code is not easier to reason about than async. I think most would agree.

      You probably think async code can't have deadlocks like threaded code can. Async is still multi-threaded it's just that the threads are done in user-space and contain an implicit global lock.

        Async is not pre-emptive though (if using a single theaded executor). And thats where most of the unintutive behaviour of threads comes from.

        Notice I didn't say async code is easier to reason about.
    • sanxiyn 6y ago
      I disagree, at least in Rust. async is hard. Threading is easy.

        Do you have something that backs up your belief?
