ThirdGreatest.js

/*

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. 


Input = "coder","byte","code" Output = "code"
Input = "abc","defg","z","hijk" Output = "abc"
