What are some common mistakes in event handling?

Some common mistakes include not properly managing event listeners, failing to debounce events, and not cleaning up after events.

Can you explain what debouncing means in this context?

Debouncing is a technique used to limit the rate at which a function is executed. For example, if a user is typing in a search box, debouncing ensures that the search function is only called after the user has stopped typing for a specified duration.

What are the consequences of not cleaning up event listeners?

Not cleaning up event listeners can lead to memory leaks and performance issues, as the listeners may continue to exist even after the elements they are attached to are removed from the DOM.

How can I properly manage event listeners in my application?

You can manage event listeners by adding them when needed and removing them when they are no longer necessary, using methods like addEventListener and removeEventListener.
