Safari Books Online is a digital library providing on-demand subscription access to thousands of learning resources.
This book uses several design elements and conventions to help you prioritize and reference the information it contains:
By the Way
By the Way boxes provide useful sidebar information that you can read immediately or circle back to without losing the flow of the topic at hand.
Did you Know?
Did You Know? boxes highlight information that can make your programming more effective.
Watch Out!
Watch Out! boxes focus your attention on problems or side effects that can occur under certain situations.
In addition, this book uses various typefaces to help you distinguish code from regular English. Code is presented in a monospace font. Placeholders—words or characters that represent the real words or characters you would type in code—appear in italic monospace. When you are asked to type or enter text, that text appears in bold.
