The difference between mouseover (bubbling) and mouseenter (not bubbling)

1. The mouseenter event is fired when the mouse moves over the element
2. Similar to mouseover (bubbling) , the difference between them is:

• mouseover will be triggered when the mouse passes through its own box, and it will also be triggered when it passes through a child box. mouseenter will only be triggered through its own box        
• The reason for this is because mouseenter does not bubble
• Matching with mouseenter and mouse leaving mouseleave   will also not bubble
