Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.

Just wondering: Do you actually use float with Espruino instead of the standard-conform double? We are thinking about the switch, because then we can use the FPUs. But this might break some people's programs.
This would explain btw why Cortex M4 is faster for you: ESP32 has a not really fast FPU.
