QUESTION
I'm a coding beginner & basically trying to modify the javascript code below (which I found online - Permutations in JavaScript?) to do the following:
- return only the permuted numbers in a mixed string & in descending order (e.g. If the provided input is: “D 3fs m4q”, then the solution should return "43, 34".
- return an error exception message if the input provided does not contain any numbers (e.g. If the provided input is: “GFA”, return null)
P.S I already figured out how to implement the descending function, however, when I try to use the .replace method to extract just the numbers in the string, it doesn't work for me. What am I doing wrong?

Answered 2021-Mar-03 at 20:49I would suggest that your best bet would be to break this into pieces. Below we have a simpler permutations
function, using the helper excluding
. And we have a function to extract the digits from a number. Then we write the main function on top of these two. That main function extracts the digits, creates the permutations, sorts them, and joins them back into a comma-separated string.
