Match Characters that Occur Zero or More Times 6

**Tell us what’s happening:

Give me idea. How to ignore empty characters?

Your code so far

let chewieQuote = "Aaaaaaaaaaaaaaaarrrgh!";
let chewieRegex = /a*/; // Change this line
let result = chewieQuote.match(chewieRegex);

Link to the challenge:

I try again with chewieRegex = /[Aa][Aa]*/. But errors still occurs:
1.Your regex should not match any characters in "He made a fair move. Screaming about it can't help you."
2.Your regex should not match any characters in "Let him have it. It's not wise to upset a Wookiee."
