What are some examples of using setTimeout in JavaScript?

Can you give me some examples of how to use setTimeout in JavaScript?

Sure! The setTimeout function is used to execute a function after a specified delay. For example, you can use it like this: setTimeout(() => { console.log('Hello after 2 seconds!'); }, 2000); This will log 'Hello after 2 seconds!' after a 2-second delay.

What if I want to call a function repeatedly with setTimeout?

You can achieve that by calling setTimeout within the function itself. For example:

function repeat() { console.log('This will repeat every 1 second'); setTimeout(repeat, 1000); }

repeat();

This will log the message every second.

Can I cancel a setTimeout call?

Yes, you can cancel a setTimeout call using clearTimeout. When you set a timeout, it returns an ID that you can use to cancel it. For example:

const timeoutId = setTimeout(() => { console.log('This will not run'); }, 2000); clearTimeout(timeoutId); // This will prevent the function from executing.

Are there any common mistakes to avoid with setTimeout?

One common mistake is not using the correct context for 'this' inside the callback function. To avoid this, you can use an arrow function or bind the context explicitly.
