In JavaScript functions, do I need to return something (true or false) ? So far, all the functions I wrote without returning anything work just fine. I’m just curious.

No; Javascript functions are not required to return a value.
If you call a function that doesn’t
returna value, you’ll getundefinedas the return value.
