When should I use event delegation in JavaScript?

Event delegation is useful when you have multiple similar elements, like a list of items, and want to manage events efficiently.

Can you give me an example of where it would be beneficial?

Sure! If you have a list of 100 items, instead of adding an event listener to each item, you can add one listener to the parent element.

What are the performance benefits of using event delegation?

It reduces memory usage and improves performance by minimizing the number of event listeners, especially in dynamic lists.

Are there any downsides to using event delegation?

Yes, it can lead to issues if the event target is not the intended element, or if you need to handle events differently for specific items.
