How does setTimeout work in JavaScript?

setTimeout is a function that executes a specified function after a given delay in milliseconds.

Can you show me an example of using setTimeout?

Sure! Here's a simple example:

setTimeout(() => {
    console.log('Hello, World!');
}, 2000);

This will log 'Hello, World!' to the console after 2 seconds.

Each call to setTimeout creates a new timer, so they will execute independently after their respective delays.

Can I cancel a setTimeout?

Yes, you can cancel it using clearTimeout. You need to store the timeout ID returned by setTimeout.
