What are common memory leak patterns in Node.js?

Common memory leak patterns in Node.js include global variables, closures, event listeners, and forgotten timers.

Can you explain how closures can cause memory leaks?

Sure! Closures can retain references to variables in their outer scope, preventing them from being garbage collected.

What about event listeners? How do they contribute to memory leaks?

Event listeners can cause memory leaks if they are not properly removed, as they keep references to the objects they are attached to.

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

You can use tools like Node.js built-in --inspect flag, Chrome DevTools, or libraries like memwatch-next to detect memory leaks.
