Building Windows 8 Apps with JavaScript is the definitive guide for every experienced developer who wants to create, ship, and profit from Windows 8 apps built with HTML5 and JavaScript. Written by Chris Sells, former Visual Studio Principal Program Manager who led the team that built Microsoft's official Windows 8 JavaScript app templates, and Brandon Satrom, expert web/mobile developer, this book covers every facet of development with Microsoft's new JavaScript framework and WinRT. The authors guide you through building full-featured Windows Store apps that merge the best aspects of desktop, web, and mobile apps into a single user and developer experience. You'll learn how to leverage the full power of the Windows 8 platform and integrate services ranging from client-side state to offline storage. Leveraging these techniques, you can deliver information to users faster, more clearly, and more concisely, on whatever devices they prefer.
