JavaScript DOM
The JavaScript Document Object Model (DOM) is a programming interface for web documents that represents the structure of HTML and XML documents as a tree of objects. It allows JavaScript to dynamically access, manipulate, and update the content, structure, and style of web pages in real-time. This enables interactive and responsive user experiences by modifying elements, handling events, and altering the document without reloading the page.
Developers should learn JavaScript DOM to build dynamic, interactive web applications, as it is essential for front-end development to handle user interactions, update content, and create single-page applications. It is used in scenarios like form validation, dynamic content loading, animations, and real-time updates, making it a core skill for web developers working with HTML and CSS.
