Tell us what’s happening:
I was able to pass with
let userCheck = /^ [^[^\d][a-z]+\d*$|^[^[^\d]\d\d+$/i;
But shouldn’t have been able to due to Rule # 1. Usernames can only use alpha-numeric characters.
I would suggest adding a test case like let username = “%z1”; to prevent this.
Your code so far
let username = "JackOfAllTrades"; let userCheck = /change/; // Change this line let result = userCheck.test(username);
