Im having a dificulty here, why should I add a “\w*” before \d{2}

let sampleWord = "astronaut";
let pwRegex =  /(?=\w{6})(?=\d{2})/;
let result = pwRegex.test(sampleWord);

because you don’t want to impose that the numbers be at the beginning of the string. The two lookaheads are not indipendent, they match from the same position.
