sortCharactersInString
Alphabetically sorts the characters in a string.
Use the spread operator (...), Array.prototype.sort() and String.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'
