Sort a string alphabetically using a function

Question

Imagine you were given a string and you had to sort that string alphabetically using a function. Example:

sortAlphabets( \'drpoklj\' ); //=> returns \'djklopr         


        

Answer 1

Newer browsers support String.prototype.localeCompare() which makes sorting utf8 encoded strings really simple. Note that different languages may have a different order of characters. More information on MDN about localCompare.

function sortAlphabet(str) {
  return [...str].sort((a, b) => a.localeCompare(b)).join("");
}

console.log(sortAlphabet("drpoklj")); // Logs: "djklopr"

If you only have to support ascii strings then the default sorting implementation will do.

function sortAlphabet(str) {
  return [...str].sort().join("");
}
