Understanding a few typographic conventions in this book will help you in your readings :
New terms are set in italics the first time they are used.
Objects, classes, properties, methods , and other "computer language" words are set in a fixed-pitch font, like so: var me:Person = new Person("Jeff","Tapper","author"); .
Any variables , objects, classes, and so on used within a paragraph are shown in code font, like this: ASampleClassName .
Any text instance that you are asked to type are set in boldface.
