Despite the fact that we've spent some time on the intrinsic
elements, we still have a lot of browser functionality that we haven't covered yet. Instead of adding numerous new methods, properties, and events to the window
object, the designers of the object model decided to group pieces of related functionality together into new objects and to make these objects children of the window
object.

We'll cover each of these subsidiary, but still important, objects over the next few pages.window
