sortCharactersInString

Alphabetically sorts the characters in a string.

• Use the spread operator (...), Array.prototype.sort() and String.prototype.localeCompare() to sort the characters in str.
• Recombine using String.prototype.join('').

const sortCharactersInString = str =>
  [...str].sort((a, b) => a.localeCompare(b)).join('');

sortCharactersInString('cabbage'); // 'aabbceg'
