Node

In the context of the DOM (Document Object Model), a node is any object that represents a part of a web document. DOM nodes form a tree-like structure, where each piece of the document—like elements, text, or comments—is a node in that tree.


Common Types of DOM Nodes

  • Element Node: Represents an HTML tag (<div>, <p>, etc.)

  • Text Node: Represents the text inside an element

  • Comment Node: Represents HTML comments

  • Document Node: Represents the root of the DOM


Example:

<div>
  Hello <span>world</span>!
</div>


This snippet contains:

  • One element node: <div>

  • One text node: "Hello"

  • One nested element node: <span>

  • One nested text node: "world"


Why It Matters

Understanding how nodes work is key to manipulating or navigating the DOM effectively—whether you're writing vanilla JavaScript or working with React's virtual DOM.
