+*  Using the JavaScript language, have the function ThirdGreatest(strArr) take the     *
+*  array of strings stored in strArr and return the third largest word within in.      *
+*  So for example: if strArr is ["hello", "world", "before", "all"] your output should *
+*  be world because "before" is 6 letters long, and "hello" and "world" are both 5,    *
+*  but the output should be world because it appeared as the last 5 letter word in     *
+*  the array. If strArr was ["hello", "world", "after", "all"] the output should be    *
+*  after because the first three words are all 5 letters long, so return the last one. *
+*  The array will have at least three strings and each string will only contain        *
+*  letters.                                                                            *
+*                                                                                      *

+*  I am going to sort the array in descending order using the length of each entry.    *
+*  Once sorted the third greatest number is in array position 2.                       *
+*                                                                                      *
+*  Steps for solution                                                                  *
+*    1) Sort array in decending order based on length of entry                         *
+*    2) Return the entry in the 3rd spot                                               *
