JavaScript Intervals and Timeouts Removing timeouts


window.setTimout() returns a TimeoutID, which can be used to stop that timeout from running. To do this, store the return value of window.setTimeout() in a variable and call clearTimeout() with that variable as the only argument:

function waitFunc(){
    console.log("This will not be logged after 5 seconds");
function stopFunc(){

var timeout = window.setTimeout(waitFunc,5000);

This will not log the message because the timer is stopped after 3 seconds.
