Alphabet Soup code challenge

/**
 * This challenge requires you to alphabetically sort the characters in a string. We'll sort the characters using the built-in array sort function.
 */

function AlphabetSoup(str) {
  // Convert the passed str into an array of chars with split then sort the array in alphabetical order
  var chars = str.split('');
  var sorted = chars.sort();
  // Return the rebuilt string
  return sorted.join('');
}

/* Shorter */

  var sorted = str.split('').sort();
  return sorted.join('');
}

/* Shortest */
function AlphabetSoup3(str) {
  return str
    .split('')
