How can I improve the performance of my async/await code?

To improve performance, consider using Promise.all for concurrent operations instead of awaiting each one sequentially.

Can you give me an example of using Promise.all?

Sure! Instead of awaiting each fetch call, you can do this:

const results = await Promise.all([
  fetch(url1),
  fetch(url2),
  fetch(url3)
]);

What if I need to handle errors for each promise?

You can use try/catch inside a loop or handle errors individually by mapping over the promises and catching errors.

Are there any other performance tips for async/await?

Yes! Avoid blocking code inside async functions and consider using web workers for heavy computations.
