Regex To Sort A String Containing Digits

Question

I have a string which contains digits. I need to sort this string using regular expression.

var myString = "85762034834126745305743";

I'm looking for a complete solution which only use regular expression. Just need your thought on this whether it can be achieved or not.

Is there a reason you would like to use regex for this task? — Oren Hizkiya

@p.s.w.g So this can only be achieved with the help of a loop ? — CodeDecode

Regular Expressions only match patterns they do not influence those matches. — Jason Sperske

Regular expressions allow you to check if a string matches a pattern, and possibly extract subsets of the string. Sorting means putting a list of items in a certain order. The two are unrelated concepts. — Adam Batkin

Regular expressions are not suited for this kind of task. Plain old JavaScript is a lot simpler and easier:

"85762034834126745305743".split("").sort().join("") // "00122333344445556677788"
