Why would I use the clearTimeout method?

I have any ideas where we can need it?

Straight from the MDN website.

A simple example would be for an alarm. I want to set an alarm for 1pm, it's currently 10pm. So let's say we had an alarm.

When I set an alarm, I want it to show an alert that says a message like 'Wake Up'. So I set it for 1pm. - Let's say the remind method just uses setTimeout(callback, timeTo10Pm) An hour later (11pm) I decided to cancel that alarm - The cancel method would need to use clearTimeout to stop it
