What is setInterval in JavaScript?

Can you explain what setInterval does in JavaScript?

Sure! setInterval is a JavaScript function that repeatedly calls a specified function at set intervals (in milliseconds).

How do I use setInterval to create a simple timer?

You can use setInterval like this: setInterval(() => { console.log('Tick'); }, 1000); This will log 'Tick' every second.

Can I stop the interval once it starts?

Yes, you can stop it using clearInterval. You need to store the interval ID returned by setInterval and pass it to clearInterval.

Can you show me an example of stopping the interval?

Certainly! Here's an example:

let intervalId = setInterval(() => { console.log('Tick'); }, 1000);
setTimeout(() => { clearInterval(intervalId); console.log('Stopped'); }, 5000);
``` This will stop the interval after 5 seconds.
