Why *w is required for this regex to work

[Metry]

I’m currently on the positive and negative lookahead lesson in the javascript curriculum, and the command is: Use lookaheads in the pwRegex to match passwords that are greater than 5 characters long, and have two consecutive digits.

Originally, my code was:

let sampleWord = “astronaut”;

let pwRegex = /(?=\w{6,})(?=\d{2})/; // Change this line

let result = pwRegex.test(sampleWord);

but that doesn’t work, and the given solution is:

let sampleWord = “astronaut”;

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

let result = pwRegex.test(sampleWord);

Why does this work? My second part looks ahead to make sure there are at least two digits right? What difference does the \w* make? I’m having trouble understanding

The two look ahead start looking from same position, so in the first version the two digits must be at the beginning
