When should I use async middleware in my application?

You should use async middleware when you need to handle asynchronous operations, like database calls or API requests.

Can you give me an example of async middleware?

Sure! An example would be using async/await in an Express.js middleware to fetch user data from a database before proceeding.

What happens if I don't use async middleware?

If you don't use async middleware, your application may not handle asynchronous operations correctly, leading to unhandled promises or delays.

Are there any performance implications?

Yes, using async middleware can improve performance by allowing your application to handle multiple requests concurrently without blocking.
