What is the order of event listeners in JavaScript?

What is the order of event listeners in JavaScript?

In JavaScript, event listeners are executed in the order they are added to the target element. This means if you add multiple listeners for the same event, they will run in the sequence they were registered.

Can you give me an example of how that works?

Sure! If you have two listeners for a 'click' event on a button, the first listener will execute before the second one. For instance:

button.addEventListener('click', firstListener);
button.addEventListener('click', secondListener);

In this case, firstListener runs before secondListener when the button is clicked.

What happens if I use event.stopPropagation()?

Using event.stopPropagation() prevents the event from bubbling up to parent elements, but it doesn't affect the order of listeners on the same element. The listeners will still execute in the order they were added.

Is there a way to control the execution order of listeners?

Yes, you can control the execution order by using the addEventListener method's third parameter, which allows you to specify whether the listener should be executed during the capturing phase or the bubbling phase.
