 In order to get the last letter of a string, you can subtract one from the string's length.
 
-For example, if `var firstName = "Charles"`, you can get the value of the last letter of the string by using `firstName[firstName.length - 1]`.

 You can use the same principle we just used to retrieve the last character in a string to retrieve the Nth-to-last character.
