The latest versions of jsdom require Node.js v6 or newer. (Versions of jsdom below v10 still work with Node.js v4, but are unsupported.)
We are using ^10.1.0
Specifically it uses destructuring assignment (const { URL } = ...) which throws an exception in Node < 6 (see http://http://node.green/)
Ideally our Node version requirements should match the rest of the services team (Parsoid/RESTBase).
