A modern programming language that makes developers happier.

After I learnt structural concurrency I realized that doing concurrency wrong in JavaScript is much easier than I thought. Most of the async function does not provide a mechanism to cancel, which means the other `Promise`s won’t be cancelled in `Promise.race`. Also `Promise.all` won’t either cancel or wait for other `Promise`s if one of them is rejected. And this language is used in every web.

I know there is `Promise.allSettled`, but it is much harder to use.

there is also `AbortController`/`AbortSignal` but basically it only works with `fetch`. JS just got stalled on figuring out how to make cancellable Promises in general

Well, it's not like those are its most severe issues.
