Credit: Pavel Khorenyan Mobile development is a big problem. Users demand mobile apps, and they often demand that these apps have native-level performance, fit, and finish. At the same time, the apps need to be delivered "yesterday," which just doesn't happen with apps written in native code. To top it all off, users expect apps to work on, at minimum,Brazil still shocked over Ney, iPhones, iPads, Android phones, and Android tablets, and they won't be completely satisfied unless a Web or desktop version also is available. Mobile Web applications are one set of solutions to the time-to-market and profusion-of-devices problems, but they have problems of their own. Mobile Web UIs aren't usually very flexible, they often can't be made to "sizzle," and they often suffer from runtime performance issues. Even worse, mobile Web apps typically don't work when disconnected and don't retain their state after a context switch -- for instance, when a user answers a phone call.

But they still suffer from performance issues. This is because the rendering of a heavily nested HTML document is inherently time-consuming and because the WebView control encapsulated by shells such as PhoneGap tends to be old and slow compared to the latest mobile browsers. Enter Famo.us
To address some (and, Famo.us hopes, eventually all) of these issues, Famo.us developed a high-performance JavaScript framework for mobile applications that looks more like an animation or a game system than like conventional Web infrastructures. Famo.us 0.1.2, currently in a controlled beta test period, already demonstrates high performance for Android and iOS mobile Web applications. Famo.us doesn't really support desktop browsers yet, except for Chrome, and there are known bugs with Safari, Firefox, and Internet Explorer. I found Famo.us reasonably easy to learn and use, but I'm a senior developer with a varied background, and I was learning and using it , where I could bring questions and issues to the developers and architects. Although Famo.us currently is being rolled out to 1,Mark- ASUP Demands Selfless, Justifiable, Articles,000 new beta testers every day, the beta is scheduled to be open to the public on May 19. The founders' vision is for there to eventually be 50 million Famo.us developers.
