Fine-grained logic in async JavaScript can be a very special kind of pain. It's a rather specialized event loop, but the vast majority of articles treat it like "oh it's just a normal in-order event loop like every other". It ain't. Unless your logic has no order requirements between async components, or explicitly accounts for things like "microtasks", there's a chance it's wrong... and it depends on your runtime: https://bytefish.medium.com/the-execution-order-of-asynchronous-functions-in-the-event-loop-ff641dae4f09 https://bytefish.medium.com/the-execution-order-of-asynchron... (it's generally better to not depend on execution order in async systems anyway, but it's rather easy for it to sneak in sometimes. if it does, it may work on your machine but not on mine, or it might change based on what kinds of tasks other code spawns, if you press a button at a critical moment, etc)
