The Document Object Model (DOM) acts as a programming interface for web documents. It represents the page structure so programs can change the document’s content, style, and structure. When a web browser loads an HTML document, it creates a DOM tree, treating every HTML element and text as a node in this tree. This allows JavaScript to access and modify parts of the webpage dynamically. For instance, if you click a button and text appears, JavaScript is likely interacting with the DOM to update the visible content. Understanding the DOM is fundamental for web development, especially for interactive web design and front-end development, enabling dynamic content updates without reloading the entire page.
