Javascript profanity match NOT replace

Question

I am building a very basic profanity filter that I only want to apply on some fields on my application (fullName, userDescription) on the serverside

Answer 1

How about with fixed regexp:

check = new Regexp('(^|\b)'+badWords.join('|')+'($|\b)', 'gi');

check.test('ass') // true
check.test('suckass') // false
check.test('mass of whore') // true
check.test('massive') // false
check.test('slut is massive') // true

I'm using \b match here to match for word boundry (and start or end of whole string).
