Javascript has landed in iOS

https://github.com/node-app/Nodelike : "implement a roughly Node.JS-compatible interface using JavaScriptCore.framework on iOS 7 and OS X Mavericks"

http://nodeapp.org/ : "Node.JS interpreter as an iOS app," 

http://blog.bignerdranch.com/3784-javascriptcore-and-ios-7/ : "JavaScriptCore gives developers deep access to the full JavaScript runtime from Objective-C. You can syntax-check and execute scripts, access variables, receive callbacks, and share Objective-C objects, making possible a wide range of interactions."

 http://strongloop.com/strongblog/apples-ios7-native-javascript-bridge/ : "Apple’s iOS7 is the first iOS operating system to officially support JavaScript as a mobile development language in Apples XCode tool chain. Apple’s iOS7 support of JavaScript inline with your Objective-C code validates JavaScript as the leading (and only) non proprietary language that is supported within the iOS development environment by the device manufacturer."
