Regular Expressions: Match Characters that Occur Zero or More Times

JavaScript
1

Tell us what’s happening:

Can’t solve this. I have tried everything I can and still can’t pass.
see the following solutions that I have tried:

Your code so far
let chewieQuote = “Aaaaaaaaaaaaaaaarrrgh!”;
let chewieRegex = /A-a*/ig; // Change this line
let result = chewieQuote.match(chewieRegex);

let chewieRegex = /A*/ig; // Change this line
…

let chewieRegex = /a*/ig; // Change this line
…
let chewieRegex = /A*/i; // Change this line
…
let chewieRegex = /a*/; // Change this line

and so on. Nothing works. What am I doing wrong?


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

Hi

What test are you trying to complete?

If you’re trying to match to whole quote, you need to also include the other characters as well.

Well, if you see this, just remember A and a are two different things for regex

4

technically this string only has one A and many a’s

Try this.

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

It matches aa with zero or more a’s followed by. Ex: aa, aaa, aaaaa etc
or

let chewieQuote = "Aaaaaaaaaaaaaaaarrrgh!";
let chewieRegex = /aa+/i; // Change this line
let result = chewieQuote.match(chewieRegex);

last one doesn’t pass the test but it is also correct. Only reason is not using * character.

This worked for me. The instructions said not to use flags.

let chewieQuote = “Aaaaaaaaaaaaaaaarrrgh!”;
let chewieRegex = /Aaa*/; // Change this line
let result = chewieQuote.match(chewieRegex);

‘let chewieRegex = /aaa*/i;’
