How does async/await affect JavaScript performance?

Async/await can improve code readability and maintainability, but it may introduce some performance overhead due to the creation of promises.

Is it always better to use async/await over callbacks?

Not necessarily. While async/await is often easier to read, callbacks can be more performant in certain scenarios, especially for simple tasks.

What are some performance tips when using async/await?

To optimize performance, avoid unnecessary awaits, use Promise.all for concurrent operations, and minimize the number of async functions.

Can async/await be used with existing promise-based code?

Yes, async/await is designed to work seamlessly with promise-based code, allowing you to refactor gradually.
