When to choose mouseover() and hover() function?

Question

What are the differences between jQuery .mouseover() and .hover() functions? If they are totally same why jQuery uses both?

Answer 1

From the offical docs: (http://api.jquery.com/hover/)

The .hover() method binds handlers for both mouseenter and mouseleave events. You can use it to simply apply behavior to an element during the time the mouse is within the element.
