What is DOM traversal and manipulation?
The Document Object Model ( DOM ) is a standard convention for accessing and manipulating elements within HTML and XML documents. Elements in the DOM are organized into a tree-like data structure that can be traversed to navigate, locate, or modify elements and/or content within an XML/HTML document.
How do you traverse through DOM?
