Какая роль у Document Object Model в веб-разработке и как она используется?

The Document Object Model (DOM) is a programming interface for HTML and XML documents that represents the structure of a page as a tree of objects. In web development, DOM allows dynamic modification of the content, structure, and styles of a page using JavaScript. For example, you can add a new element, change text, or handle user events. It is the foundation of interactivity on web pages.
