I'm one of those insane people that actually likes Javascript, so I tend to actually flash espruino to my ESP8266 chips unless they need to be battery powered (where compiled is still the only way to get them to last long enough in most cases). But I did try out lua and quite enjoyed it (lua being another of my preferred languages), and never really felt the need to tryout micropython. How is performance with micropython? and how does it differ from "regular" python?
