Node.js compile

We would like to transpile and a couple of small ES6 code to ES5. This is part of a traditional server side web project with an Ant build file.

Part of the ant build starts a Node.js script which transpiles the ES6 script in this project to ES5. This script is not functioning correctly.

We would like help to get this to work correctly and creating a test so that we can ensure this executes.
