How do I clear a setInterval in JavaScript?

How do I clear a setInterval in JavaScript?

You can clear a setInterval using the clearInterval() function. You need to pass the interval ID that was returned by setInterval.

Can you show me an example?

Sure! Here's a simple example:

let intervalId = setInterval(() => {
    console.log('This will run every second');
}, 1000);

// To clear the interval
clearInterval(intervalId);

What happens if I don't clear it?

If you don't clear it, the function will continue to execute at the specified interval, which can lead to performance issues or memory leaks.

Is there a way to stop it after a certain condition?

Yes, you can use a condition inside the interval function to call clearInterval when the condition is met.
