Well, if you literally have to leverage TONS of third party libraries, most of which are incompatible, then I would at least be glad that my code, the ui framework, the date handling library, the routing library, the ajax and the validation library, was all written using compatible and immutable by default code.

It's better to have a problem with some dependencies, than to have an issue with your entire codebase. So yes, I would argue that clojurescript has value.
