How can I prevent memory leaks in Node.js?

To prevent memory leaks in Node.js, you should regularly monitor your application's memory usage, use tools like Node.js's built-in profiler, and ensure that you properly manage event listeners and closures.

What tools can I use to monitor memory usage?

You can use tools like Node.js's built-in --inspect flag, Chrome DevTools, or third-party libraries like clinic.js and memwatch-next.

Can you explain how closures can cause memory leaks?

Closures can cause memory leaks if they hold references to variables that are no longer needed, preventing garbage collection from freeing up memory.

What are some best practices to avoid memory leaks?

Some best practices include avoiding global variables, cleaning up event listeners, and using weak references when appropriate.
