What is event delegation in JavaScript?

Can you explain what event delegation is in JavaScript?

Sure! Event delegation is a technique that allows you to attach a single event listener to a parent element instead of multiple listeners to individual child elements.

Why is event delegation useful?

It's useful because it improves performance by reducing the number of event listeners in the DOM, and it also allows you to handle events for dynamically added elements.

Can you give me an example of how to implement event delegation?

Absolutely! For instance, if you have a list of items, you can add a click event listener to the parent <ul> element and handle clicks on its <li> children.

What are some common use cases for event delegation?

Common use cases include handling clicks on lists, managing form inputs, and responding to events on dynamically generated content.
