How can I avoid memory leaks when using closures in JavaScript?

To avoid memory leaks with closures, ensure that you don't unintentionally hold references to variables that are no longer needed.

Can you give me an example of a memory leak caused by closures?

Sure! A common example is when a closure retains a reference to a DOM element that is removed from the document, preventing garbage collection.

What are some best practices to prevent this issue?

Best practices include using weak references, cleaning up event listeners, and avoiding global variables.

Are there tools to help detect memory leaks in my code?

Yes, tools like Chrome DevTools and memory profiling libraries can help you identify and fix memory leaks.
