[Resolved] Comma identified as a vowel in Regex match

Tell us what’s happening:

Hey, I am on Regular Expressions - Match Single Character with Multiple Possibilities now . I am looking for vowels in a string, but somehow I get a comma in a search result. Anyone knows what’s going on here?

(26) [“e”, “a”, “e”, “o”, “u”, “i”, “e”, “a”, “o”, “e”, “o”, “e”, “I”, “a”, “e”, “o”, “o”, “e”, “i”, “o”, “e”, “,”, “o”, “i”, “e”, “i”]

Your code so far

let quoteSample = "Beware of bugs in the above code; I have only proved it correct, not tried it.";
let vowelRegex = /[a,e,i,o,u]/gi; // Change this line
let result = quoteSample.match(vowelRegex); // Change this line

Figured out my mistake. No comma needed inside []. Sorry for the post.
