DOM navigation in JavaScript is the process of moving through the elements and nodes of a webpage's Document Object Model (DOM) to access, traverse, and manipulate elements dynamically.

Key Points :

1.Tree Structure: The DOM is hierarchical, with parent-child relationships.

2.Child Elements: Use children, firstElementChild, lastElementChild.

3.Parent Elements: Access with parentElement.

4.Sibling Elements: Use nextElementSibling, previousElementSibling.

5.All Nodes: Use childNodes, firstChild, lastChild for all node types (text, comment, element).

6.Live Collections: DOM collections (e.g., children) update in real-time.

7.Manipulation: Traverse elements to modify content, attributes, or styles.
