Show HN: LazyPromise = Observable – Signals

https://github.com/lazy-promise/lazy-promise
14•ivan7237d•5d ago
A Promise-like primitive which is lazy/cancelable, has typed errors, and emits synchronously instead of on the microtask queue. In a way LazyPromise is what you get if you take an Observable and make it impossible to misuse it for what the Signals were built to do.

Interesting, interesting. It would take me a few hours of playing with this mechanism to know what I think of it as a primitive, but for me this solution is relevant to a problem I really have so I might take a look. Right now I just write methods that sometimes return a promise and sometimes don't.
