ECMA-419: The ECMAScript Embedded Systems API and J5e
summary
ECMA-419 defines a concrete, callbacks-first API for GPIO, PWM, ADC, serial and other hardware primitives and a provider model so the same code runs on local pins or a remote device. J5e implements Johnny-Five–style peripheral classes (LED, servo, switch, sensor, GPS, I2C expander) and bundles code for deployment to ESP8266/ESP32 microcontrollers so programs run standalone with no host server. Engines like XS and Moddable provide the JS runtime; there are ~3,800 embedded devs versus ~240,000 web devs, and demos boot and run when power is applied.
