What is the difference between a calling function and a called function?

The buildCipher function could create more complicated alphabets. As long as both the receiver and the sender generate the alphabet in the same way, the message needs to only include the keyword for encoding and decoding to work. Try building these variations:
1. Put the keyword at the end of the alphabet, rather than the front: Note: This is accomplished simply by changing the final line. 2. Reverse the alphabet before concatenating it to the keyword: Note: This is accomplished by adding a reversal of the “rest” variable prior to concatenating. 3. Separate the vowels and the consonants in the rest of the alphabet so that the cipher alphabet is keyword, then the rest of the vowels, then the rest of the consonants: Note: We can simply duplicate the work from 3.9 to achieve the desired effect.
