what is a DOM

Comment

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.

A web page is a document that can be either displayed in the 
browser window or as the HTML source. In both cases, it is the 
same document but the Document Object Model (DOM) representation 
allows it to be manipulated. As an object-oriented 
representation of the web page, it can be modified with a 
scripting language such as JavaScript.
