The Document Object Model (DOM) is a programming interface for web documents. It represents the page so that programs can change the document structure, style, and content. The DOM represents the document as nodes and objects. That way, programming languages can interact with the page.

JavaScript is often used to manipulate the DOM, because it is a language that can interact with HTML and CSS, both of which are used to create web pages. Using JavaScript, you can create dynamic web pages that can respond to user interactions and events.

The DOM is organized as a tree-like structure called the “DOM tree.” Each element, attribute, and text node in an HTML document is represented by an object in the DOM tree, and you can use JavaScript to manipulate those objects.

For example, you can use JavaScript to add a new element to the page, modify the text inside an existing element, or change the style of an element. This makes it possible to create interactive web pages that can respond to user actions, like clicking a button or hovering over an image.

Overall, the DOM is a powerful tool for web developers, because it allows them to create dynamic and interactive web pages that can respond to user actions in real-time.
