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' 

What would be the best way to do this?

Answer 1

You can use array sort function:

var sortAlphabets = function(text) {     return text.split('').sort().join(''); }; 

STEPS

1. Convert string to array
2. Sort array
3. Convert back array to string

Answer 2

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(""); }
