Regex error : Restrict possible usernames

[chrispbacon]

Tell us what’s happening:
The freecodecamp’s compiler is matching the following regex : /[a-zA-Z][a-zA-Z]|[a-zA-Z]+[0-9][0-9]+|[a-zA-Z][a-zA-Z]+[0-9]+/

with string : “c57bT3”

Edit : My question is the compiler shouldnt match the above regex with the string above.( I tried matching this regex with the string on https://regexr.com and it didn’t match there)

Your code so far

let username = "JackOfAllTrades";
let userCheck = /[a-zA-Z][a-zA-Z]|[a-zA-Z]+[0-9][0-9]+|[a-zA-Z][a-zA-Z]+[0-9]+/; // Change this line
let result = userCheck.test(username);

Welcome, crispbacon.

@chrispbacon

the compiler shouldnt match the above regex with the string above.

The regex provided should match because it is testing for:

• [a-zA-Z][a-zA-Z]+[0-9]+

This matches: c57

Also, I see regexr.com matches:

Hope this clarifies
