Tell us what’s happening:
Describe your issue in detail here.
I have tried my code on the editor many times and it doesn’t seem to work. I tried to troubleshoot it with console.log but it returns, what seems to me, the correct solution. Could someone please tell me what is the problem?

  **Your code so far**

function rot13(str) {
var ans = '';
function de_code(boi) {
  let num = 13;
  boi.toUpperCase();
  const theAlphabet = 'abcdefghijklmnopqrstuvwxyz';
  let index = theAlphabet.toUpperCase().indexOf(boi);
  let index_Num = (index + num)%26;
  if(theAlphabet.toUpperCase().includes(boi)) {
    return theAlphabet.toUpperCase()[index_Num]
  }else {
    return " ";
  }
}
for(let i = 0; i < str.length; i++) {
  console.log(de_code(str[i]))
}

}

rot13("SERR PBQR PNZC");

function rot13(str) {
var endCode = ‘’;
function de_code(boi) {
let num = 13;
boi.toUpperCase();
const theAlphabet = ‘abcdefghijklmnopqrstuvwxyz’;
let index = theAlphabet.toUpperCase().indexOf(boi);
let index_Num = (index + num)%26;
if(theAlphabet.toUpperCase().includes(boi)) {
return theAlphabet.toUpperCase()[index_Num]
}else {
return " ";
}
}
for(let i = 0; i < str.length; i++) {
endCode += de_code(str[i])
}
console.log(endCode);
}

rot13(“SERR PBQR PNZC”);

This is my updated code… Still doesn’t work

your answer seems to be correct but you forget to add all the results back to the string

ans += de_code(str[i])

and there is is another thing its other special characters than space
like ! in the second test

You have to use return statement
return endCode

Thanks for the suggestion
