Sign function has a while loop that does nothing with the result

[arucker1021]

 var result = [];
      var current;

      while (!(current = it.next()).done) {
        result.push([current.value[1], characters[i]]);
        i++;
      }

      // TODO Test utf8ToUint8Array function
      var messageAsUint8Array = utf8ToUint8Array(partialToken);

This block of code in the signJWT function does nothing with the result that it iterates over. I was also not able to get a JWT with a verifiable signature but wanted to mainly point out that the above code seems useless
