jQuery travesing refers to a process of moving through the DOM to find specific HTML elements. This search depends on the relations between elements. jQuery provides multiple methods for traversing the DOM conveniently and dynamically.
With jQuery traversing, you can easily move up (ancestors), down (descendants), and sideways (siblings) in the tree, starting from the selected (current) element. This movement is called traversing - or moving through - the DOM tree.
An ancestor is a parent, grandparent, great-grandparent, and so on.
A descendant is a child, grandchild, great-grandchild, and so on.
Siblings share the same parent.
