Implements and uses functions to calculate the averageRanking of objects and to sort objects by ranking

objects.js

 * Sorts an array of object by ranking
 * @param {array} objects The array containing objects to sort by ranking
 */

 * Calculates the average ranking of objects
 * @param {array} objects The array containing objects whose average ranking is to be calculated
 */

    (total, currentObject) => (total + currentObject.ranking),
    0,
  );
  const averageRanking = totalRanking / objects.length;
  return averageRanking;
}

/**
 * Generates an array of random objects
 * Its added here just to test the first two functions
 * @param {number} number The number of random objects to generate
 */
