Cross-platform application design provides an excellent starting point for mastering application development in this new book. You can introduce today's most popular technologies, including HTML5, CSS3, JavaScript, jQuery Mobile, Node.js, JSON, localStorage, sessionStorage, NoSQL using MongoDB, SQL using MySQL, templating using handlebars, and maps. An app-centric view emphasizes subsets of these technologies to guide students in developing non-trivial apps. The apps serve as models for numerous projects from various application domains, while detailed outlines present potential course projects. Apps continue to evolve, but the technologies in this book form the backbone for future cross-platform app development. Students learn to work with all major mobile and web platforms as this book's active learning approach asks students to type code in parallel as the apps are developed. Meaningful exercises further encourage students to change code and evaluate resulting app behavior.
