Attending node.js events does not mean you are technical. A lot of people, I would say most people in my experience, go those events to connect with technical talent.
It would probably take me 20 minutes or so, and would be very maintainable and not make anyone's eyes bleed. I'm not willing to put that 20 mins in to prove my point, but I am certain that the unmaintainable code vomit which they have as an example on their website took much longer than that.
