JS Dom intro


The Document Object Model (DOM) is a programming interface for web documents. It represents the structure of a document (like HTML or XML) as a hierarchical tree of objects, making it possible to manipulate the content, structure, and style of a webpage dynamically using JavaScript.


Key Features of the DOM

Dynamic Content: Modify webpage content on the fly without reloading the page.

Interactive Behavior: Add event listeners to make elements interactive.

Structure Manipulation: Add, remove, or rearrange elements.


DOM Tree Structure

Document Node: The root node (e.g., document).

Element Nodes: Represent HTML elements (e.g., <div>, <p>).

Attribute Nodes: Represent element attributes (e.g., class="example").

Text Nodes: Represent text content inside elements.
