Explain DOM (Document Object Model)?

The Document Object Model (DOM) is an extensible markup language (XML) and HTML (HyperText Markup Language) programming interface. It outlines the logical organisation of documents as well as how they may be accessed and changed.

Web documents have a programming interface called the Document Object Model (DOM). So that software can alter the document's structure, appearance, and content, it serves as a representation of the page. Programming languages can communicate with a page by interacting with the nodes and objects that the DOM uses to represent the document.
