What's the difference between 'mouseenter' and 'mouseover' events?
mouseenter and mouseover have a key difference in their behavior: mouseenter doesn't bubble and only triggers when the mouse enters the target element, while mouseover bubbles and triggers when entering the element or any of its children. Similarly, mouseleave doesn't bubble while mouseout does. This makes mouseenter/mouseleave more suitable for tracking mouse movement over a specific element without dealing with its children.
