Promises are much better than you think
summary
Argues that Promises outperform Async/Await for many real problems and demonstrates the claim with concrete code: uses Promise.all, Promise.any and allSettled and race to run tasks in parallel, pick the first success, gather every result, or timeout slow requests, shows how async/await serializes loops while Promises enable controlled concurrency, and builds a tiny promiselike “something/nothing” implementation with split flip stitch and getUser that reproduces chaining and error propagation so the example works end to end.
