Why does it need to be clear? That is the point - I'm challenging people to think, solve, see what's happening and digest the code - and yeah I know some people won't like it. In fact I want those people to hate it. I have a sore spot with the "entitlement crowd" who need everything wrapped up sweetly with a bow - the ones who sit on their laptops in the back of the room, geek out on Twitter, and then give your talk a low rating because it was "boring slides".

Is it hard to figure out that it's CoffeeScript? I don't think so - specifically because I said that it was CoffeeScript in the beginning. You just had to read it :).

And yes! Strings resolve to true :). Madness that people got to figure that out with some code, and not a bullet point slide!
