The Document Object Model (DOM) is a standardized interface provided by web browsers to represent and programmatically manipulate structured documents, especially HTML and XML documents. It describes the hierarchical structure of a document as a tree, where each node represents an element, attribute, or text.
Tree Structure:
<html> element, with child nodes such as <head>, <body>, <div>, <p>, etc.Object-Oriented Representation:
Interactivity:
<p> element or insert a new <div>.Platform and Language Agnostic:
1. Accessing an Element:
let element = document.getElementById("myElement");2. Changing Content:
element.textContent = "New Text";3. Adding a New Element:
let newNode = document.createElement("div");
document.body.appendChild(newNode);The DOM is defined and maintained by the W3C (World Wide Web Consortium) standards and is constantly updated to support modern web technologies.
