Looking at js/lil.js I first thought it was a minified file, then realized it’s probably not optimized to save bytes, but to save pixels on the screen, to fit more of the code at a glance. I find it surprisingly appealing and feel a little sad thinking that this style of formatting wouldn’t pass code review anywhere.
You may also be interested in oK[0], which is developed by the same person who created Decker, which has a similar style, although more clean and a little bit more readable IMO than LIL.
