I have finished the challenge but I am still confuse a bit so could someone explains me what’s happening behind the scene???

I meant the code explanation of this regex:

 /(?=\w{5,})(?=\D+\d{2})/

Your code so far

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