How do async/await and timers work together in JavaScript?

How do async/await and timers work together in JavaScript?

Async/await allows you to write asynchronous code that looks synchronous. Timers like setTimeout can be used with async/await.

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

Sure! Here's a simple example:

function delay(ms) {
  return new Promise(resolve => setTimeout(resolve, ms));
}

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

example();

What happens if I don't use await with a promise?

If you don't use await, the promise will execute asynchronously, but your code will continue running without waiting for it to complete.

Are there any common pitfalls when using async/await?

Yes, common pitfalls include forgetting to use await, which can lead to unhandled promise rejections, and not handling errors properly.
