Tell us what’s happening:
I have written the Regex for the challenge Restrict Possible Usernames as below. When I run the regex and try to run all the tests on my own i.e. by printing them:
console.log(result)
console.log(result2)
but somehow the regex fails one test i.e. Your regex should not match J
. I don’t know why that’s happening. So, Can anybody suggest me anything?
Your code so far
let username = "J";
// Usernames have to be at least two characters long.
// Username letters can be lowercase and uppercase.
let userCheck = /^[a-z][a-z]*[0-9]*$/i; // Change this line
let result = userCheck.test(username);
let result2 = username.match(userCheck)
console.log(result)
console.log(result2)
// /^(?=^abc)(?=.*xyz$)(?=.*123)(?=^(?:(?!456).)*$).*$/
// /(?=([a-z][a-z]*))(?=([0-9]$))/ig
// [0-9]$
// /^[a-z]{2,}\d*$/i
// /[a-z][a-z]*[0-9]$/ig
// Usernames have to be at least two characters long
