Having watched the 1 minute long video i still don't know what these guys do. Also the "JavaScript God Mode" tagline is completely meaningless, better change it to something that's actually descriptive of what they do. What the heck is a "JavaScript God Mode" anyway? At first sight it sounds like they compete with pkg https://github.com/zeit/pkg https://github.com/zeit/pkg but i've never heard of them before, so I'm guessing maybe I'm misunderstanding what they do. Can anyone provide some interpretations on what this actually does, and what makes it unique?
