Missing Letters test not passing. My code seems to be returning the correct values

JavaScript
#1

I’m having trouble passing the tests here. Perhaps there’s a serious bug in my program or maybe there are more fcc tests that I’m not aware of?

// Current code

function fearNotLetter(str) {
  let currentChar;
  let value;
  for (let length = str.length - 1; length > 0; length-- )
  {
    currentChar = str.charCodeAt(length)
    previousChar = str.charCodeAt(length - 1);
    if (currentChar - previousChar > 1)
    {
      value = String.fromCharCode(currentChar - 1);
    }
  }
  return value;
}

Each test locally returns the same values as type string which are displayed on the website. when all letters exist undefined is returned… I know my code can be tightened up and it’s not the best, but not sure here why my code isn’t passing any tests?

Thanks

Make sure you declare all used variables.

previousChar is not defined.

that’s the error I see when I log your function
