Found this awesome snippet above at SO by user @rndme I really want to know how it works but I can't seem to find any contact info on either SO nor github and I'm not allowed to comment on SO. Here's hoping to him seeing this gist 😃

I get the part where you pass regex.test to filter but the second arg /i/ is to be used as this and that's what puzzles me.
