DOM stands for Document Object Model. It is a programming interface for web documents that provides a structured representation of the document as a tree-like structure. The DOM defines the objects and properties of a web page, allowing programmers to dynamically access and manipulate the content, structure, and style of the page.
In other words, the DOM is a standard programming interface for web documents. It defines the logical structure of documents and the way a document is accessed and manipulated. The DOM is not a programming language, but rather a set of rules and guidelines for how different programming languages can interact with and modify the structure and content of web pages.
