Is setInterval heavy?
No, setInterval is not CPU intensive in and of itself. If you have a lot of intervals running on very short cycles (or a very complex operation running on a moderately long interval), then that can easily become CPU intensive, depending upon exactly what your intervals are doing and how frequently they are doing it.
Is setInterval asynchronous?

How do you stop setInterval in react hooks?

How do you execute a setInterval function without delay for the first time in JavaScript?

What is setInterval?

This method returns an interval ID which uniquely identifies the interval, so you can remove it later by calling clearInterval() .
How do I know if clearTimeout has worked?
Just set t to 0 (or t in your case) in your timeout function: timeoutID = 0; If you use clearTimeout it sets the timeout id to 0, so checking for timeoutID === 0 will check if it’s either been been cleared or completed.
