Many design patterns work perfectly well in Javascript. In web architectures, there is a practical problem with where logic lives, where the data lives, and what generates the "view". It's a non trivial architectural problem, but it's not impossible by any means. The computer science and software is completely capable. I guess this is tangential to the debate about if Javascript is _good_ for MVC. If code is executed on both the server and the browser there probably needs to be a clean separation of responsibility or code generation. Otherwise - Google gears and chrome OS can certainly make the entire app live completely client side (and in MVC/ JS).
