What are some common debugging issues in Node.js?

Some common issues include callback hell, unhandled promise rejections, and memory leaks. Would you like to know more about any specific issue?

Can you explain callback hell?

Callback hell occurs when you have multiple nested callbacks, making the code hard to read and maintain. Using Promises or async/await can help.

What about unhandled promise rejections?

Unhandled promise rejections happen when a Promise is rejected but there's no .catch() to handle the error. This can crash your application.

How can I prevent memory leaks in my Node.js application?

To prevent memory leaks, ensure you properly manage event listeners, avoid global variables, and use tools like Node.js's built-in memory profiling.
