Use recursive setTimeout in place of setInterval

[schontz]

setInterval is known to create a backlog of tasks if the run loop gets busy. Why not to use setInterval highlights the issue. Consider using a recursive setTimeout instead.

Something like this:

function setIntervalSafe(fn, ms) {
  let timer;
  const wrapper = (isSetup) => {
    if (!isSetup) fn();
    timer = setTimeout(wrapper, ms);
  }
  wrapper(true);
  return () => clearTimeout(timer);
}

const stopInterval = setIntervalSafe(() => console.log(Date.now()), 1000);
// ...
stopInterval();
