Document Object Model (DOM)

Document Object Model (DOM) is a fundamental concept in web development that allows for the dynamic modification and manipulation of HTML and XML documents. It provides a tree-like representation of the document's structure, enabling developers to access and interact with its elements, content, and attributes programmatically.
Understanding the DOM
The DOM is a hierarchical structure that mirrors the HTML document's organization. Each element in the HTML document corresponds to a node in the DOM tree. Elements can have attributes, which are represented as properties of the node, and they can also have child nodes, which represent the elements contained within them. This hierarchical structure allows for precise and efficient access to any part of the document.
DOM manipulation involves accessing and modifying nodes within the DOM tree. This can be achieved using various methods provided by JavaScript, the primary programming language used for web development. Developers can add, remove, or update elements, change their attributes, and modify their content dynamically, allowing for interactive and dynamic web applications.
