Improve interoperability with other languages

[Krever]

I would like to have an interpreter that will be easy to be used from javascript. So we can release a library written in scalajs and call it from javascript like any other library. It's mostly doable right now but scalajs encoding of case classes is too far away from js one and I also don't know how easy it is to call object method from js. Does anyone know how we could achieve that?

I would like to also use this issue to have a discussion on:

• Is our interoperability with Java good enough? Can you use any of our client interpreters from Java without many problems?
• Can we somehow improve cross-platform support in general? Right now the user has to rely on openapi+swagger-codegen to call endpoints API from other languages like go or c++.
