How to exit from setInterval

Pass the value of setInterval to clearInterval.

const interval = setInterval(() => {
  clearInterval(interval);
}, 1000)

Demo

The timer is decremented every second, until reaching 0.

let secondsRemaining = 10

const interval = setInterval(() => {

  // just for presentation
  document.querySelector('p').innerHTML = secondsRemaining

  // time is up
  if (secondsRemaining === 0) {
    clearInterval(interval);
  }

  secondsRemaining--;
}, 1000);

<p></p>

Use clearInterval:

var refreshId = setInterval(function() {
  var properID = CheckReload();
  if (properID > 0) {
    clearInterval(refreshId);
  }
}, 10000);
