This book is for developers, ideally with web development experience, who are interested in developing for the emerging mobile market, but do not want to learn a new SDK for every phone on the shelf. Readers should be comfortable with JavaScript, HTML, and CSS, and interested in learning the new advances in those technologies that allow for rich, native-style experiences.
