- CryZe 2y agoI still don't know why that isn't just provided for you.
- sebstefan 2y agoYou're returning a promise, that's a red function. It's async https://journal.stuffwithstuff.com/2015/02/01/what-color-is-your-function/ https://journal.stuffwithstuff.com/2015/02/01/what-color-is-... Sleep() should halt, this returns immediately If I want my code to actually halt, I can either make myself red and use await on your red function, or I resign myself to put everything after the sleep in a .then()
- iudqnolq 2y agoI misread your comment. It wouldn't make sense to have a non-async sleep in a browser, as it is an event-loop based primarily single-threaded JavaScript runtime.

- jitl 2y agoI just found out you can sync sleep in JavaScript. I’m using it to implement multi-process sync file locks that need to interoperate with a large non-async framework (eslint). Atomics.wait(this.sleepBuffer, 0, 0, ms)
