What are the performance implications of using closures in JavaScript?

What are the performance implications of using closures in JavaScript?

Closures can lead to increased memory usage because they maintain references to their outer scope. This can impact performance.

Can you explain how closures affect garbage collection?

Closures can prevent garbage collection of variables in the outer scope, as long as the closure is still in use, leading to potential memory leaks.

Are there scenarios where using closures is beneficial despite the performance cost?

Yes, closures can encapsulate state and create private variables, which can lead to cleaner and more maintainable code.

How can I optimize my code if I'm using closures?

You can minimize the use of closures in performance-critical sections, or use techniques like memoization to reduce overhead.
