9.3 Summary

 The Document Object Model (DOM) is a programming API for HTML and XML documents.
 The Document Object Model currently consists of two parts, DOM Core and DOM HTML.
The DOM Core represents the functionality used for XML documents, and also serves as
the basis for DOM HTML.

 The objects are self-contained bundles of data.
 Object tag is used to include objects such as images, audio, videos, Java applets, ActiveX,
PDF, and Flash into a webpage.

 The M in DOM stands for Model, but it could just as easily stand for Map.
 A Node is an interface from which a number of DOM types inherit, and allows these
various types to be treated (or tested) similarly.

 The Document object is the root of a document tree. The Document object gives us access
to the document’s data.

 By using JavaScript, we have the ability to create dynamic web pages. Events are actions
that can be detected by JavaScript.
