Does the version ( j2v8 4.7.1 for linux) support ES6 import, new features?

I want to load javascript which is using ES6 import and "new" features. Does j2v8 support ES6?

It uses node 7.4.0 so one needs to check what exact;y V8 version is in this nodejs version.

It builds on V8 version 5.4.500.45. I don't know if this version supports import. If anyone has some time to try this out and post the answer, that would be greatly appreciated.

I am pretty sure: v8 5.4.x does support ES6 imports, in version 6 they already focus on rest spread operator... (kinda ES7)

I just tested it, and unfortunately the answer is no.

    @Test
    public void testImport() {
        String jsCode = "import * as foo from './foo'\n"
                + "let y = foo.square(5);\n"
                + "y;";
        System.out.println(v8.executeIntegerScript(jsCode));
    }

This fails with a compilation error on the symbol import. I also found this while searching the issue, which appears to state that import / module support is not yet available in V8 5.4.

As I've often said, we are bug for bug, feature for feature compatible with V8. We can do as much as V8, but no more.
