How do I prevent default actions in events

In JavaScript, to prevent the default action of an event, you can use the event.preventDefault() method. This is particularly useful when you want to stop the browser's default behavior for certain elements, such as preventing a form from submitting or a link from navigating to a new page.

For example, if you want to prevent a form from submitting when a button is clicked, you can attach an event listener to the button and call preventDefault() within the event handler function.

<script> document.getElementById('myButton').addEventListener('click', function(event) { event.preventDefault(); // Prevents the default form submission console.log('Form submission prevented!'); }); </script>
