Subsequent calls will return the average of all of the non-null elements.

Example:

const mAvg = require('./js-utils/movingAverage.js');  // Include the script in your nodejs code

var tempAverageC = mAvg.Avg(60);             // Return a function to Average over 60 elements
var avgC = tempAverageC(20.1);               // Return the current average when you pass in the 
                                             //  next value to average

console.log('Temp Average: ' + avgC.toFixed(1) + '\xB0C');

Outputs to the console:

Temp Average: 20.1°C

Example:

const random = require('./js-utils/getRandom.js');                  // Include the script in your nodejs code

                                                           //  1 and 10 (inclusive)
