Tell us what’s happening:

can someone explain the usage of \w and the usage of \D*\d

Your code so far


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

Try the awesome tool: https://regexr.com/
Copy paste the expression and you’ll find an explanation for every single part of your regular expression. If you click on them, you’ll even find examples!
And if it is still fuzzy, you can always come back here!
