  • I Avoid Async/Await
    7 projects | news.ycombinator.com | 16 Apr 2022
    Async/Await covers the 80% of use cases for async logic in JS. Most people aren't really using promises as multicast references. They don't call `then` in one place, hang on to the promise reference, then call `then` again somewhere else (perhaps to represent a cached value); they call `then` once on the reference because it's just a moment in a composite operation.

    It's for this reason that I think this library[0] is the more appropriate abstraction for that same 80% of use-cases, as its more memory efficient since you can represent the same composite operation that generates multiple promise references with a single object (a unicast reference instead). I haven't learned Rust but apparently the author bases this on Rust's ownership principle.
