Regular Expressions - Reuse Patterns Using Capture Groups

JavaScript
1

Tell us what’s happening:

let reRegex = /^(\d+) \1\s\1$/; // and
let reRegex = /^(\d+)  \1 \1$/; //pass the test but
let reRegex = /^(\d+) \s\1\s\1$/;  //not. It should be all or nothing.

Your code so far

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