You can also pause the timer at any time using the 'Pause' button. It is a free and easy-to-use countdown timer. You can reset the timer at any time using the 'Reset' button. The timer will alert you when it expires. Press the 'Start' button to start the timer. args) allow us to run the func once/regularly after delay milliseconds. A countdown timer for 1 minute and 20 seconds. That limitation comes from ancient times and many scripts rely on it, so it exists for historical reasons.įor server-side JavaScript, that limitation does not exist, and there exist other ways to schedule an immediate asynchronous job, like setImmediate for Node.js. The similar thing happens if we use setInterval instead of setTimeout: setInterval(f) runs f few times with zero-delay, and afterwards with 4+ ms delay. You choose how many hours, minutes or seconds the timer should last. The 4+ ms obligatory delay between invocations comes into play. Set a countdown timer for 1 hour and 9 minutes and well alert you when it expires. Use this timer to easily time 17 Minutes.
