How accurate is the `pause` function, and what precision cam I “guarantee”? What’s the minimum pause time?\*

I’m working on a project and I the smallest delay I need will be `~0.02` seconds (20 milliseconds). I only care about the simulator in the browser, not on hardware.

\*Obviously, if your computer is really slow than the delays won’t be as accurate and/or much longer.

Hmm… pretty accurate. It’s just like a countdown. I used the timer on my phone and set to see how good it was.

Yea, did a bunch of tests, seems reliable enough.
