Tell us what’s happening:
Describe your issue in detail here.
Not sure exactly what I am doing wrong the error it is giving me is Your regex should not match the string

42\t42\t42

.

Your code so far

let repeatNum = "42 42 42";
let reRegex = /^(\d+)\s\1\s\1$/; // Change this line
let result = reRegex.test(repeatNum);
console.log(result)

You should not match any space character (like the tab character for example should not be matched).

Use only a single space in the match

sorry but i need a little more help ive tried for a while to figure this out now

Okay, so \s doesn’t just match whitespace. It matches tab characters too and if we think about what the \t in the 42\t42\t42 string means…?

Remember you can represent a space character in a regex by using a space character.

E.g.
/ /.test(" ");
(returns a value of true)
