I agree with you about ES6 - very much in many ways it's captured the best of the syntax from languages like groovy without relaxing so much that things become ambiguous etc. Nonetheless, I find JavaScript still simply isn't structured enough and doesn't have the ability to tap into the underlying strengths of the JVM ecosystem. Static compilation has improved enormously incidentally, which to me means I almost never drop into Java any more where I used to code 50/50 in Groovy / Java. Mind you, if all you want is ES6 on the JVM, you already have a pretty good subset of it in Nashorn / JDK9. I don't know how well it can use Node libraries though ...
