I'm unable to pass Only one test Z97 if anyone can help

Only one test case left. I’m unable to pass it.

let username = "JackOfAllTrades";
let userCheck = /(^\D)([a-zA-z]{1,})(\d*$)/i; // Change this line
let result = userCheck.test(username);

So, you are saying that after the first char, there must be at least one char? That is why “Z97” is failing.

First of all, sites like regex101.com are a great tool for working out these things.

Secondly, I think testing this will involve a little bit of logic. You have two possibilities for what the second char is. Are you familiar with the OR operator in regex, |?


Yes, I’m familiar with or operator.
