Are you sure that works for all languages? I think it's just that the Javascript/Typescript plugins are made available to all IDEs.

It certainly used to be (and I believe its still the case) that the "major" language plugins besides JS are only usable in their specific IDE or in IDEA Ultimate (which can run all of them) (i.e. PHP w/ PHPStorm, Ruby w/ RubyMine and Python w/ PyCharm)
