DOM

The Document Object Model (DOM) is a programming interface for web documents that represents the structure of HTML or XML documents as a tree of objects. It allows programming languages like JavaScript to dynamically access, manipulate, and update the content, structure, and style of web pages in real-time.

Also known as: Document Object Model, DOM API, DOM Tree, Web DOM, HTML DOM

Why learn DOM?

Developers should learn the DOM to build interactive and dynamic web applications, as it enables client-side scripting for tasks like form validation, content updates without page reloads, and responsive UI changes. It is essential for front-end web development, particularly when working with frameworks like React or vanilla JavaScript to handle user interactions and data rendering.
