What are some real-world examples of event propagation?

Event propagation refers to the way events flow through the DOM in web development. A common example is when you click a button inside a div; the click event can trigger both the button's and the div's event handlers.

Can you give me more examples?

Sure! Another example is when a user hovers over a menu item, which can trigger a tooltip to appear. The hover event propagates from the menu item to its parent elements.

How does event propagation differ from event bubbling?

Event propagation includes both capturing and bubbling phases. In bubbling, the event starts from the target element and bubbles up to the root, while capturing goes from the root down to the target.

Are there any performance considerations with event propagation?

Yes, excessive event listeners can lead to performance issues. It's important to manage event propagation wisely to avoid unnecessary processing.
