Answer 1

Convert ms to hh:mm:ss

function millisecondsToHuman(ms) {
  const seconds = Math.floor((ms / 1000) % 60);
  const minutes = Math.floor((ms / 1000 / 60) % 60);
  const hours = Math.floor((ms  / 1000 / 3600 ) % 24)

  const humanized = [
    pad(hours.toString(), 2),
    pad(minutes.toString(), 2),
    pad(seconds.toString(), 2),
  ].join(':');

  return humanized;
}
