Using module.exports in node.js

decon_t1_calledFile.js

// make data available to decon_t1_callingFile.js
module.exports = function(){
	console.log('Output from file decon_t1calledFile.js');
};

decon_t1_callingFile.js

// get input from file called 'decon_t1_calledFile.js'
var someInput = require('./decon_t1_calledFile.js');

// display contents of someInput
someInput();

This works
