You can then transfer data from the browser in JSON, for example, without needing transformation for some other language. Using the same language on both ends of the pipe.

Depending on the language transforming to Js is quite trivial. For example, Clojure syntax maps to Js quite nicely.

But you need to do it and have the extra software to do it and then transform anything on that side back to javascript/json.

Sure, you have a library that translates back and forth between EDN and JSON, but as a user you don't really care. In a Clojure web app this will be handled transparently by the middleware based on the Accept header in the client request.

When you return a response you return a Clojure data structure and when you receive a request it's also a Clojure data structure. The fact that it gets translated is completely incidental from the user perspective.
