In response to this, I read the spec of setTimeout, bu I couldn't find the part where implementations may have an upper bound. Can someone more familiär with the specs point me in the right direction?


Adding a comment here to check back later because I'm curious now if someone has the answer. I thought it would be easy to find the answer, but I can't find it either. I figured it would say somewhere a number is converted to an int32, but instead I got to the part where there's a map of active timers[1] with the time stored as a double[2] without seeing a clear loss happening anywhere before that.

Just JS being JS: setTimeout(()=>{}, Infinity) executes immediately


Thanks, but I'm looking for the specification of this behaviour.
