This is the answer, but I don’t understand why do I need to the /w* in the second part of this positive logahead?

let sampleWord = “astronaut”;

let pwRegex = /(?=\w{6,})(?=\w*\d{2})/gi;

let result = pwRegex.test(sampleWord);

Why do i need to use this shorthand again? Surely I should just be specifyinh that its two numbers, why do I need another \w
