Cancel kill window.setTimeout() before it happens

javascript

You can cancel a setTimeout() using the clearTimeout() method. The setTimeout() function returns an ID which can be used to identify the timeout and cancel it using clearTimeout(). Here’s an example:

// Set a timeout for 5 seconds
const timeoutId = window.setTimeout(() => {
  console.log('Timeout completed.');
}, 5000);

// Cancel the timeout before it happens
window.clearTimeout(timeoutId);

In this example, we first set a timeout using setTimeout() for 5 seconds and store the returned ID in a variable called timeoutId. We then use clearTimeout(timeoutId) to cancel the timeout before it happens.

It’s important to note that the clearTimeout() method only works if it’s called before the timeout occurs. If you call clearTimeout() after the timeout has already occurred, it won’t have any effect.
