What does preventDefault do in JavaScript?

The preventDefault method is used to prevent the default action of an event from occurring. For example, it can stop a form from submitting.

Can you give me an example of how to use preventDefault?

Sure! If you have a form submission, you can use preventDefault like this:

form.addEventListener('submit', function(event) {
    event.preventDefault(); // Prevents the form from submitting
    // Your custom logic here
});

Are there any situations where I shouldn't use preventDefault?

Yes, you should avoid using preventDefault if you want the default action to occur, like submitting a form or following a link.

What other event methods are similar to preventDefault?

Other similar methods include stopPropagation, which prevents the event from bubbling up the DOM, and stopImmediatePropagation, which stops other listeners from being called.
