I'm not quite sure what you're looking for here - did you want me to explain all the optimization techniques I used? If so, that's a pretty tall order. I could write pages and pages about that (although I don't have time to at the moment ). There are many, many different techniques that all combine to make the code run more efficiently - there's not really one thing I could point to that is the magic sauce that makes things super fast. There are architectural choices, memory management, lookup efficiencies, and plenty of regular JS code optimizations at play. Code optimization is a rather deep topic and a quick Google search should give you a lot of information. Maybe I misunderstood your question, though, so let me know if there's something specific you were looking for.
