Chapter 12. Objects and Classes > Built-in ActionScript Classes and Objects

12.8. Built-in ActionScript Classes and Objects

We've really come a long way since Chapter 1. Our first exposure to ActionScript was a simple perusal of the items in the Actions panel. Since then, we've studied data and expressions, operators, statements, and functions; and now we've explored the concept of classes and objects. It's time to put the final brush strokes on the picture we've been painting of the ActionScript language.

ActionScript comes with a variety of syntactic tools: expressions contain data; operators manipulate data; statements give instructions; and functions group instructions into portable commands. They constitute ActionScript's grammar, but until now, our vocabulary has been very limited. The built-in classes and objects of ActionScript fill that void and give us lots of interesting things to talk about.
