Regular Expressions - Restrict Possible Usernames False Pass Condition

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);
