FWIW I do not think ES6 modules are a good solution for your problem. Since they are not in browsers, you would effectively be adding a layer of indirection (the “transpilation” James discusses) that serves no purpose besides to beta-test a future platform feature for us. There are much more straightforward ways of solving your problem, i.e. I see no reason to go Java -> JavaScript that doesn’t work in browsers -> JavaScript that works in browsers. Just do Java -> JavaScript that works in browsers.

All modern browsers currently support ES5 (ECMAScript, 5th Edition) and some parts of ES6. IE7-8 supported ES3 (ES4 was rejected, so supporting ES3 was really only being 1 version behind at the time). In ES6, there is [finally] a syntax introduced for importing and exporting "modules" (libraries, etc.). For some quick examples, you can peek at the ECMAScript wiki<http://wiki.ecmascript.org/doku.php?id=harmony:modules_examples>. A transpiler is a tool that can take code written in one version of the language syntax and convert it to another [older] version of that language. In the case of ES6, you'd want to look into using es6-module-transpiler<http://esnext.github.io/es6-module-transpiler/> to convert ES6-style imports/exports into an AMD (asynchronous module definition)<https://github.com/amdjs/amdjs-api/blob/master/AMD.md> format. That is, of course, assuming that your Java2Script translation could be updated to output ES6 module syntax.

I realize that what I am doing is pretty wild -- direct implementation of Java in JavaScript -- but it is working so fantastically. Truly a dream come true from a code management point of view. You should check it out. As far as I can see, what I would need if I did NOT implement async throughout Jmol is a suspendable JavaScript thread, as in Java. Is that on the horizon? Bob Hanson
