Can anyone show me how to use a switch statement to solve Caesers cipher challenged. I have tried ths code below but it does not work. Can anyone help

rot13(str) { 
var code = "";

switch {switch (str) {
case 'A':
answer = "N";
break;
case 'B:
answer = 'O';
break;
case 'C':
answer = "P";
break;
case 'D:
answer = 'Q"';
break;
case 'E:
answer = "R";
break;
case 'F:
answer = 'S';
break;
case 'G':
answer = "T";
break;
case 'H:
answer = "U";
break;
case 'I':
answer = "V";
break;
case 'J:
answer = 'W';
break;
case 'K':
answer = "X";
break;
case 'L:
answer = 'Y"';
break;
case 'M:
answer = 'Z"';

}
return str; 
}

I cleaned up your code.
You need to use triple backticks to post code to the forum.
See this post for details.

You have missing single quotes in various places in your code (like in 'B, 'D, etc).

You’ll also have to use a loop to iterate over each letters in the string.

Your code could look like

function rot13(str) {
  var code = '';

  for (...) {
    switch (letter) {
      case 'A':
        // add 'N' to `code`
        break;

      case 'B':
        // add 'O' to `code`
        break;

      ...
    }
  }

  return code;
}

Part of your text is blurred. I cannot see it

It’s blurred because it’s a spoiler (contains a solution). Just click on it to remove the blur.

Ah… ok I will not touch it until I figure it out.

You can use for loop to solve this cipher.

If you still can get it checkout this https://github.com/Deityhub/Caesars-Cipher/blob/master/Cipher.js for a rundown of how thr code works.
