what does " /[aeiou]/gi " do in this code?

Question

function disemvowel(str) {
return str.replace(/[aeiou]/gi, '');
}

Answer 1

It's regular expression. "[aeiou]" tells the replace function to look for any of these characters and "gi" are flags that tells the function to look for match over the entire string (will otherwise break at the first match), this is the "g" flag. And the "i" flag tells it to match case insensitively. So, it would also match, A , E and so on.
