How do async timeouts work in Node.js?

In Node.js, async timeouts can be managed using the setTimeout function, which allows you to execute a function after a specified delay.

Can you give me an example of using setTimeout with async/await?

Sure! You can wrap setTimeout in a Promise to use it with async/await like this:

const delay = (ms) => new Promise(resolve => setTimeout(resolve, ms));

async function example() {
    console.log('Waiting...');
    await delay(2000);
    console.log('Done!');
}
example();

What happens if I use setTimeout inside a loop?

If you use setTimeout inside a loop, it will create multiple timers that execute after the loop completes. This can lead to unexpected behavior if not handled properly.

How can I control the execution order of multiple timeouts?

You can control the execution order by chaining Promises or using async/await to ensure that each timeout completes before the next one starts.
