What are some real-world examples of event delegation?

Event delegation is a technique in JavaScript where a single event listener is added to a parent element to manage events for multiple child elements. A common example is a list of items where clicking on any item triggers the same event.

Can you give me a specific example with code?

Sure! Here's a simple example:

const list = document.getElementById('myList');

list.addEventListener('click', function(event) {
    if (event.target.tagName === 'LI') {
        alert('Item clicked: ' + event.target.textContent);
    }
});

In this code, clicking any list item will trigger the alert.

What are the benefits of using event delegation?

The benefits include improved performance by reducing the number of event listeners, easier management of dynamic elements, and cleaner code.

Are there any drawbacks to event delegation?

Yes, potential drawbacks include event bubbling issues and the need to ensure that the parent element is present in the DOM before adding the listener.
