Tell us what’s happening:
I am having trouble with this challenge. One of the test cases is “8pass99”, and I am not sure how to make sure only two consecutive digits are matched.

Your code so far


let sampleWord = 'astronaut';
let pwRegex = /^\D(?=\w{5})(?=\w*\d{2})/; // Change this line
let result = pwRegex.test(sampleWord);
