Promises are, technically speaking, "abstracted crap".

So is abstracted crap only ok if it's already in the JS standard library?

Promises proved themselves in libraries before they got added to Javascript.

Signals have, too. And it is literally spelled out in the readme, in the introduction section

I hate promises. Writing:

let result; let error; await blah .then(r=>result=r) .catch(e=>error=3) .final(callback(err, result));

Is disgusting.
