@tomraithel Yeah, I felt the same when it was still available for free. As awesome as it is (or seems to be), it distracts me from doing what I initially intended to do.
@kentcdodds Cool article. It can be very helpful in some situations.
I have a newbie question though. You wrote in the TS implementation comment that TS doesn't have Intl.ListFormat yet. I'm confused - shouldn't all JS code be valid in Typescript? Thus it should have Intl. ListFormat?
