JavaScript all the things
summary
Runs JavaScript on tiny microcontrollers: a 64 KB RAM / 200 KB ROM VM (JerryScript) already running on ~40 boards and on $1 Bluetooth-capable chips; a 96 MHz board with 256 KB RAM runs the stack and reads sensors, toggles 40 LEDs, and serves a BLE heart-rate monitor to phones while surviving on a coin cell for a year. Development-side tooling uses browser-based simulation and cross-compilation with Emscripten and a web simulator, plus on-device ML via Micro Tensor, and the demos work end-to-end.
