Stuck On Javascript Username Generator

I am trying to create a system username that consists of the first alphabetic characters found in the Family name, street address, Given name; the numerical day of the month; and t

Solution 1:

Try changing

addy=addy.replaceAll("[0-9]","");

with

addy = addy.replace(/[0-9]/g, "");

Or, to get the first letter (not number, symbol, etc.), use:

addy = addy.replace(/[^A-Za-z]/g, "");

Good luck!
