I have finally completed the challenge, has been a tough week :sweat_smile:

for(let x = 0; x < unicodes.length; x++) {
    result += String.fromCharCode(unicodes[x]);
}

The final error was that the final loop was adding a whitespace character to the end of the string so changed the iteration to < rather than <=.

Thanks for all your help guys :slight_smile:

Final solution:

function rot13(str) { // LBH QVQ VG!

  let unicodes = [];
  let result = "";

for(let i = 0; i < str.length; i++) {
  if(str.charCodeAt(i) >= 0 && str.charCodeAt(i) <= 64) {
    unicodes.push(str.charCodeAt(i));
  } else if(str.charCodeAt(i) >= 65 && str.charCodeAt(i) <= 77) {
    unicodes.push(str.charCodeAt(i) + 13);
  } else if(str.charCodeAt(i) <= 90) {
    unicodes.push(str.charCodeAt(i) - 13);
  } 
}

for(let x = 0; x < unicodes.length; x++) {
    result += String.fromCharCode(unicodes[x]);
}
//console.log(result);
return result;
}

// Change the inputs below to test
rot13("SERR PBQR PNZC");
