ts2c is a JavaScript/TypeScript‑to‑C transpiler that converts source code into readable C89, aiming to let developers write IoT‑oriented firmware in JS/TS while generating lightweight native C suitable for low‑memory microcontrollers. It works via a CLI, Node module, or in‑browser bundle, currently supporting about 70 % of ES3 (mostly statements/expressions) and targeting platforms such as ESP32, ESP8266, AVR and MSP430. The project is geared toward embedded programmers who want the convenience of JavaScript syntax without the overhead of a full JS interpreter.
