Solution seems to work locally, but not on website

Tell us what’s happening:
I am running the tests locally and they all seem to pass, but they do not pass in the app. What is wrong with my code?

  **Your code so far**

function rot13(str) {
  let arrayifiedString = str.split('');

  for (var i = 0; i < arrayifiedString.length; i++) {
    thisCharCode = getCharCode(arrayifiedString[i]);
    console.log(thisCharCode);
    if (isCapitalLetter(thisCharCode) === true) {
      arrayifiedString[i] = getNewLetter(thisCharCode);
    }
  }

  return arrayifiedString.join('');

  function getCharCode(letter) {
    return letter.charCodeAt(0);
  }

  function isCapitalLetter(letterCharCode) {
    if (letterCharCode > 64 && letterCharCode < 91) {
      return true;
    }
    return false;
  }

  function getNewLetter(charCode) {
    if (charCode > 77) {
      return String.fromCharCode(charCode - 13);
    } else return String.fromCharCode(charCode + 13);
  }
}

console.log(rot13('GUR DHVPX OEBJA SBK WHZCF BIRE GUR YNML QBT.'));

thisCharCode

This variable is not declared.

In general, I recommend developing in ‘strict mode’.

Also, I recommend against using var.

[lasjorg]

It should show you ReferenceError: thisCharCode is not defined in the editor console, are you not seeing that?

As hinted at, the tests run in strict mode.

huh… surprised node let me run this. But that is the problem.
