Currently some aspects of prototype inheritance are implemented. One day Cupertino.js should support an ECMA standard http://www.ecmascript.org - the Javascript spec that most web browsers implement. Once this is finished it would have "full" support of the language, minus any vendor added functionality.

I think porting apps might require some refactoring around the UI layer or adding functionality that is only exposed by native frameworks. It may be interesting to look into supporting hybrid web frameworks in the future :)

Yes, once Cupertino becomes more ECMA compliant, we will see the release of specific JavaScript frameworks targeting the creation of Cocoa apps. Kudos for Cupertino.js!
