How to make a permanent condition check without pausing the code?

Question

Node.js

I tried to check through an infinite loop in the main file (I know, stupidly, but this is the only thing that came to mind then). I was looking for something like this on the Internet, but I didn’t find anything (or I just didn’t scroll through the Google pages). So far, the only idea in my head is to make a separate file with this check through a loop.
Thanks in advance.

Move your validation to a separate thread. There, through setInterval, perform a check and, according to some condition, send a message to the parent thread. And in the parent thread, subscribe and wait for the event.
