Question

Is there any way to call a function periodically in JavaScript?

Answer 1

The setInterval() method, repeatedly calls a function or executes a code snippet, with a fixed time delay between each call. It returns an interval ID which uniquely identifies the interval, so you can remove it later by calling clearInterval().

var intervalId = setInterval(function() {
  alert("Interval reached every 5s")
}, 5000);

// You can clear a periodic function by uncommenting:
// clearInterval(intervalId);
