What is the difference between clearInterval and clearTimeout?

What is the difference between clearInterval and clearTimeout?

clearInterval is used to stop a function that was set to run repeatedly with setInterval, while clearTimeout stops a function that was set to run once after a delay with setTimeout.

Can you give me an example of each?

Sure! For clearTimeout, you might have:

let timer = setTimeout(() => { console.log('Hello!'); }, 1000); clearTimeout(timer);

And for clearInterval:

let interval = setInterval(() => { console.log('Tick'); }, 1000); clearInterval(interval);

When should I use clearInterval over clearTimeout?

Use clearInterval when you want to stop a repeated action, like updating a clock, and clearTimeout when you want to cancel a single delayed action.

Are there any performance implications of using these functions?

Yes, using clearInterval and clearTimeout helps prevent unnecessary function calls, which can improve performance and resource management in your application.
