Reuse Patterns Using Capture Groups [using 2 capture groups]

JavaScript
1

Tell us what’s happening:
I was wondering: if we allow using 2 capture groups (Its not the case but lets suppose it), then the following solution would be valid?

Your code so far


let repeatNum = "42 42 42";
let reRegex = /^(\d+)(\s)\1\2\1$/
let result = repeatNum.match(reRegex)
console.log(result)


let reRegex = /^(\d+)(\s)\1\2\1$/

let result = repeatNum.match(reRegex)

console.log(result)
