Learn how clearInterval() method works here

The JavaScript clearInterval() method is a method from the DOM Window object that you can use to stop the function that you execute using the setInterval() method.

For example, the following fnLog() function that runs every 1 second under setInterval() method:

let timer = setInterval(fnLog, 1000);

function fnLog() {
  console.log("Function fnLog executed");

To stop the fnLog() function above from running forever, you call the clearInterval() method:


With that, the fnLog() function will stop executing.

Both the browser and Node.js has the clearInterval() method implemented, so you can use the method on both environments.
