What is the purpose of setTimeout in JavaScript?

setTimeout is used to execute a function after a specified delay, allowing for asynchronous code execution.

Can you give me an example of how to use setTimeout?

Sure! Here's a simple example:

setTimeout(() => {
    console.log('Hello after 2 seconds!');
}, 2000);

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

What happens if I set the delay to 0?

If you set the delay to 0, the function will be executed as soon as possible, but still after the current call stack is cleared.
