What are the best practices for using event listeners in JavaScript?

Some best practices include using event delegation, removing listeners when not needed, and keeping your functions small.

Can you explain event delegation?

Event delegation is a technique where you attach a single event listener to a parent element instead of multiple listeners to child elements.

Why is it beneficial to remove event listeners?

Removing event listeners helps prevent memory leaks and improves performance by reducing unnecessary function calls.

What about using anonymous functions for event listeners?

Using anonymous functions can make it harder to remove listeners later, so it's often better to use named functions.
