What are the differences between event listeners and event handlers?

What are the differences between event listeners and event handlers?

Event listeners are functions that wait for an event to occur, while event handlers are the functions that respond to those events.

Can you give me an example of each?

Sure! An event listener might be element.addEventListener('click', myFunction), and the event handler is function myFunction() { /* code to execute */ }.

Are there any performance differences between them?

Yes, using event listeners can be more efficient, especially when you need to manage multiple events on the same element.

When should I use one over the other?

Use event listeners when you need to attach multiple events or when you want to remove them later. Use handlers for simpler, one-off events.
