Lookaheads Exercise - Help!

Tell us what’s happening:

Okay, so all the tests have been passed except for the one that says there needs to be two lookaheads. But haven’t I already used two lookaheads? I’m confused. :neutral_face:

Your code so far

let sampleWord = "astronaut";
let pwRegex = /^\D+(?=\w*\d(?=\d)){4,}/; // Change this line
let result = pwRegex.test(sampleWord);

Challenge: Positive and Negative Lookahead

Link to the challenge:

the tests are looking for pattern (?=...)(?=...) where the dots mean any character of any length
Also, a quantifier following a lookaround serves no purpose, and can safely be removed from the regular expression

you could find that unnesting the lookarounds you will not pass some tests
