This question explores JavaScript and addresses practical considerations related to: How can I prevent event bubbling in JavaScript?

Event bubbling is a process where an event propagates from the target element up through the DOM tree. To prevent this, you can use the "stopPropagation" method on the event object. Here's a simple example: Click Me document.getElementById('child').addEventListener('click', function(event) { event.stopPropagation(); alert('Button clicked!'); }); document.getElementById('parent').addEventListener('click', function() { alert('Parent clicked!'); }); ADDITIONAL COMMENT: - The "stopPropagation" method is called on the event object within the child element's event listener. - This prevents the event from bubbling up to the parent element. - The alert "Parent clicked!" will not be shown when the button is clicked. - Always ensure you have a valid reason to stop event propagation to avoid unexpected behavior in complex applications. ✅

Event bubbling is a process where an event propagates from the target element up through the DOM tree. To prevent this, you can use the "stopPropagation" method on the event object. Here's a simple example:

<!-- BEGIN COPY / PASTE -->
        <div id="parent">
            <button id="child">Click Me</button>
        </div>

        <script>
            document.getElementById('child').addEventListener('click', function(event) {
                event.stopPropagation();
                alert('Button clicked!');
            });

            document.getElementById('parent').addEventListener('click', function() {
                alert('Parent clicked!');
            });
        </script>
        <!-- END COPY / PASTE -->

Additional Comment:

The "stopPropagation" method is called on the event object within the child element's event listener.
This prevents the event from bubbling up to the parent element.
The alert "Parent clicked!" will not be shown when the button is clicked.
Always ensure you have a valid reason to stop event propagation to avoid unexpected behavior in complex applications.
