I bought this book to find out how to print variables from a javascript to a web page. Sounds simple, right? Sounds like page #1, right? Not only does this book never tell you how to do this simple and very basic operation, it pretends that no such thing could ever be expected from a book on scripting! It tells you how to print variable to popup widows and that's it. It pretends that this is all the output any person using JavaScript would or should ever need. They never address output to the web page itself. Never even mention it. Not once. That's just what I need to do with my arrays, print them to a popup alert window. I would have appreciated at least a small message as to *why* they don't tell you about such simple and basic stuff. This book is really pretty bad. I suggest you try another one on JavaScripting. It's bad, and it's disingenous.
