How to remove setTimeout from code

Currently I have setTimeout placed on here,

Which activates after the curtains close.

The curtains close after clicking the exit button,

Which appears on the screen after the curtains have opened.

https://jsfiddle.net/prcx3wyk/

  function removePlayer(player) {
    setTimeout(function() {
      player.destroy();
    }, 8000);
  }

How would I be able to remove setTimeout from the code?

just clear the interval in js clearInterval(“you’r function name which you want to stop or remove”)
