> Those were two different questions. The Scala one asked what JVM language would you learn next, if you were to learn one
Indeed. I wonder if the result is a bit misleading, because many Java developers may not really have considered other languages, and Scala is the most well-publicised. So the question may just translate to "name another JVM language." Kinda reflects with Groovy too, which has been around quite a while now and does well in this question, despite not being very "popular" in the various language league tables.
