"Hello world" i am trying to solve a problem from codewars and i am really struggling with regex. First of all i want to say sorry if my question is not properly written or maybe (dumm question).So to the point

the pin codes cannot contain anything but exactly 4 digits or exactly 6 digit and not symbols like (-)

  if ((pin.match(/^[0-9]+$/) != null && pin.length === 4) || pin.length === 6)
    return true;
  else return false;
} 
console.log(validatePIN("-12345"));// this should be false.It is true because it contains the "-" and length===6

[Here](https://stackoverflow.com/a/61767778/3832970) is the regex. – Wiktor Stribiżew May 08 '22 at 20:13
Your `()` are in the wrong place. It should be: `if (pin.match(/^[0-9]+$/) != null && (pin.length === 4 || pin.length === 6))`. – MikeM May 08 '22 at 20:17
