I consider going with Objective-J, instead writing plain JavaScript. But I wonder if the documentation of the language and the frameworks is good enough, since it seems like a very young development.
Been trying it for future development. One thing for sure, it is intended for web "apps" instead of web "sites".
Documentations are lacking at this moment I think but the mailing list is active. The only docs & howtos I can find are in the official site.
Very young development indeed.
