JavaScript - HTML DOM

The HTML DOM (Document Object Model) is a programming interface for HTML documents, which allows you to access, modify, and manipulate the content and structure of a web page using JavaScript.

The Document Object Model (DOM) connects web pages to scripts or programming languages by representing the structure of a document—such as the HTML representing a web page—in memory. Usually it refers to JavaScript, even though modeling HTML, SVG, or XML documents as objects are not part of the core JavaScript language.

When a web page is loaded, the browser creates a DOM of the page, which is a hierarchical tree-like structure where each HTML element is represented as a node in the tree. This tree-like structure is called the Document Object Model (DOM).

Using JavaScript, you can access, modify and manipulate these HTML elements, attributes, and their content. For example, you can change the content of an HTML element, change the style of an element, add or remove elements from the DOM, and handle events like clicks, mouseovers, etc.

The HTML DOM provides a standard set of properties and methods for working with HTML elements and their content, making it easier to create dynamic and interactive web pages.
