- 6. 6 Ways JavaScript is Revolutionizing the Client/Server Relationship #1 Device Access within the Browser • Adobe Cordova (phoneGap) • Device API is now defunct. • getUserMedia/Stream API (no native IE support ... yet?) • GeoLocation API broad support (except IE8) • Device Orientation, Device Motion, (poorly supported / hacky) The Client Gets Smarter. JavaScript Device APIs continue to evolve, allowing more access to device hardware, services and applications such as the camera, microphone, system sensors, native address books, calendars and native messaging applications.

But, the paradigms are still quite different. Next steps are shared APIs. DEVCON5 HTML5 Summit 5 OCT 2012 26 Wednesday, November 28, 12
