Question with comma {5,} and lookaheads

Tell us what’s happening:
This is the code and it works but I do have some questions regarding the \w{6}
Shouldn’t {5,} work?
I thought adding the , will mean “or more”.

Secondly, on the second part of the lookahead,
\w+ and \w* seems to work.

Can you enlighten me on this topic more? Thank you!

Your code so far
let pwRegex = /(?=\w{6})(?=\w+\d{2})/

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

yes, {5,} means 5 or more, but the instructions where more than 5
