Can Espruino's interpreter get extensions that would allow specific boost of performance for MCU embedded applications? (because maybe supporting type strong C var types to complement the flex var type of Jscript?)
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.
