How can I improve the performance of my Node.js Express application?

There are several strategies you can use to enhance the performance of your Node.js Express app. Would you like to focus on code optimization, middleware usage, or server configuration?

Let's start with code optimization.

Great choice! You can optimize your code by minimizing synchronous operations, using asynchronous functions, and avoiding blocking the event loop. Have you implemented any of these techniques yet?

I haven't. Can you explain how to use asynchronous functions?

Sure! Asynchronous functions allow your code to run without waiting for previous operations to complete. You can use async/await syntax to handle asynchronous code more easily. Would you like a code example?

Yes, please provide a code example.
