How do I use java library in es6 version of javascript? [closed]

I want to use a java library in a javascript written in ES6. I tried j2v8 and nashorn, but they are not supporting ES6 features. Is there any other way to do the same?

Answer

The most recent builds of J2V8 (4.7.1) is built with V8 5.4.500.45. I’m not sure what ES 6 features V8 5.4.500.45, but J2V8 will be “bug for bug” / “feature for feature” compatible with that.

J2V8 is just a wrapper around V8, so it only supports as much or as little as V8 does.
