While ES6 does add some interesting features to the language, people have done

It adds essential features to the language like "let" and "const" which
prevent nasty variable hoisting surprises! JavaScript is a flawed
language but an important one. Technologies like Node have enabled a new
wave of isomorphic applications and full stack developers. What is
interesting is new technologies hitting the browsers like asm.js so
client side code can be written in any language. JavaScript will not go
away anytime soon but better languages will replace it in the coming
decades.
Java 8 contained Nashorn with ES5 support.
Java 6 & 7 contained the Rhino JavaScript engine (although at what level of
Javascript, I forget at the moment). You could also use the external Rhino Jars if
you needed a version later than the embedded Rhino version.
I remember being surprised several years ago at how well JavaScript (using
Rhino) ran on z/OS.

ES6 is essential as it
turns JavaScript into a reasonable language. Those poor souls without a
zIIP might be a bit gun shy of running Java though!
