What is the suggested approach to declare global and call it from other units (functions).

Thank you guys:

Following NisHera request, here is the structure of my framework.

Every driver script has the following:

- Requires libs

- Reads config.js

- Parses data from Excel into variables to be used in the script

	/**
	*	require
	*/
        var spLib = require("spLib");
.........
..........

	/**
	* READING FROM CONFIG FILE
	*/
	var envConfig = require("config_env");
	var urlAUT = envConfig.url;
	var environment = envConfig.environmentName;
......
......
	/**
	* READING EXCEL
	*/
	var testdataArray = [];
	var myDataSet = spUtils.ReadFromExcel(datafilefromconfig,         datasheetfromconfig, sPath, function(data){return data;});
	var dataToSplit = myDataSet.split(",");
	for (i in dataToSplit)
	{
		testdataArray.push(dataToSplit[i]);
	}
	var count = dataToSplit.length;
	var adminName= dataToSplit[0];
......
......

I would like for these variables that I create from reading the excel sheet, to be globally available to any driver script. In other words - I want to eliminate the need to keep reading the excel file everytime I create a driver script.

So, much like we export (module.exports) our functions making them available to all AND require (require) them from a calling function -- I would like to be able to make a variable "global" and have the ability to call it from any script.

I hope this makes sense.

Thank you
