The USP of this book is that it is a one stop shop. In it is everything the complete novice needs to learn how to create web apps using HTML5, CSS3 and JavaScript (and PHP and MySQL too if they intend to use Ajax). And then there are free downloadable Objective C and
Java wrappers on the accompanying website, with which you can turn these web apps into standalone apps for the iTunes App Store and Android Market. There is no need for any other books or any previous knowledge.
