web templates the nJ operator to create objects from JavaScript
classes in the Immediate Solutit section "Creating

classes, 1|| the Date and Math classes in which you have
to create your own objects before you can use them.
We'll free web templates see how
that works in the Immediate Solution section "Creating

We've seen that web templates the document object refers
to the current page, but how do actually use such an object?
Well, we've already seen one way, which is to object methods.

basics of JavaScript programming, and in, we'll work with
the built-in objects.
