Explain rot13 javascript.

2020 TypeScript Version:

A shift argument must be given, but you can choose 13 for rot13 javascript or any other number.

// Caesar Cipher
const caesarCipher = (string: string, shift: number) => {
  // Alphabet
  const alphabet: string = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
  // Encoded Text
  let encodedText: string = '';
  // Adjust Shift (Over 26 Characters)
  if (shift > 26) {
    // Assign Remainder As Shift
    shift = shift &;
  }
  // Iterate Over Data
  let i: number = 0;
  while (i < string xss=removed xss=removed xss=removed xss=removed>

    // Special Characters
    else {
      // Append To String
      encodedText += string[i];
    }
    // Increase I
    i++;
  }
  return encodedText;
};

Example #1:


console.log(caesarCipher('ABCDEFGHIJKLMNOPQRSTUVWXYZ', 2));
Output:
CDEFGHIJKLMNOPQRSTUVWXYZAB
Example #2:
console.log(caesarCipher('GUR DHVPX OEBJA QBT WHZCRQ BIRE GUR YNML SBK.', 26 + 13)); 

Output:THE QUICK BROWN DOG JUMPED OVER THE LAZY FOX.
