How do I clear a timeout in JavaScript?
You can clear a timeout in JavaScript using the clearTimeout()
function. You need to pass the timeout ID that was returned by setTimeout()
.
Can you show me an example?
Sure! Here's a simple example:
let timeoutId = setTimeout(() => {
console.log('This will not run');
}, 2000);
clearTimeout(timeoutId);
What happens if I don't clear it?
If you don't clear it, the function inside setTimeout()
will execute after the specified delay, even if you no longer need it.
Is there a way to check if a timeout is still active?
JavaScript doesn't provide a built-in way to check if a timeout is active. You would need to manage that state manually.
