Nodejs Random Number Get getRandom(low, high)

Method Source Code

// modifying the prototype of the number objects.


Number.prototype.getRandom = function(low, high){
   //from   w  w w.  j av a  2 s  .c  om
   'use strict';

   // hacking overloading
   if((low === undefined) || (high === undefined)){

   }

   //calculate the random number
