有没有办法使用 JavaScript 找到不匹配的字符？

Question

recently I found that we can find all vowels character using regex function like this

const vowel = str.match(/[aiueo]/gi);

But is there any way to find all non vowels character using this match function?

So when I have word "thanks"

It will count all non vowel character length, so the result will be 5

Maybe anyone would share this information, I was trying to find in google, but still not found any good solution

Thanks

Putting the ^ character in front of a character set negates the set

const notVowel = str.match(/[^aiueo]/gi);
