+*  Using the JavaScript language, have the function FirstFactorial(num) take the num   *
+*  parameter being passed and return the factorial of it (ie. if num = 4,              *
+*  return (4 * 3 * 2 * 1)). For the test cases, the range will be between 1 and 18.    *                                                     *
+*                                                                                      *
+*  SOLUTION                                                                            *
+*  You can either use an iterative or recursive function to solve this challenge.      *
+*  I am going to use an interative function. I am going to start with a value of 1     *
+*  for my total and then keep multiplying it by the next number until I reach num.     *
+*                                                                                      *
+*  This function needs to account for a possible outlier - One and Zero.               *
+*  If num is 1 or 0 then the answer is 1. By setting tot to value of 1 at              *
+*  initialization, then it guaranteees that 1 will be returned if num is ever 0 or 1.  *
+*  Steps for solution                                                                  *
+*    1) Set var tot to 1.                                                              *
+*    2) Loop from 2 to num and multiple tot by num to get new tot.                     *
+*    3) Return tot for answer.                                                         *
+*                                                                                      *
