Caesars Cipher - FreeCodeCamp JavaScript Projects (Rot13)

Caesars Cipher challenge from the freeCodeCamp Javascript projects You can find this project in the freeCodeCamp javascript Data Structure and Algorithms curriculum. find more from https://freeCodeCamp.org/learn Source Code - https://github.com/CharlesKasasira/Js-DSA-projects-freecodecamp-/blob/master/Caesars-Cipher.js Question: A common modern use is the ROT13 cipher, where the values of the letters are shifted by 13 places. Thus A ↔ N, B ↔ O and so on. Write a function that takes a ROT13 encoded string as input and returns a decoded string. All letters will be uppercase. Do not transform any non-alphabetic character (i.e. spaces, punctuation), but do pass them on.
