Representation of a Document

The DOM is a standard API exposed by the browser in which a displayed page has a treebased
structure. Each node in the logical tree corresponds to an object. On the other hand,
the name “Document Object Model” hints at an object model in the common interpretation
of the object-oriented design terminology. A Web page—the document—is modeled through
objects. The model includes the structure and behavior of a document. Each node in the logical
tree is not static data; rather, it is a live object with a known behavior and its own identity.
