Restrict Possible Usernames struggle

Tell us what’s happening:
I still can’t match the string “JACK” in challenger :frowning: Plz help, thanks in advance

Your code so far

let username = "JackOfAllTrades";
let userCheck = /.+\D/gi; // Change this line
let result = userCheck.test(username);

Your browser information:

User Agent is: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36.

Link to the challenge:

Remove the g flag.

let userCheck = /.+\D/gi;

returns true when I run it against your username “JackOfAllTrades” and also against “JACK”
