As indicated in node.js displays "undefined" on the console node will say undefined intentionally and is not usually an issue.
The answer https://stackoverflow.com/a/18487887/631619 indicates that you can set
module.exports.repl.ignoreUndefined = true;
However when in node I find module.exports (with tab completion) but there is no "repl" namespace within it.
How to address this and turn off the undefined message ?
node is 4.2.6
