An Overview of the Cangjie Language

on YouTube ↗22m

" summary

Cangjie is a new statically typed, garbage‑collected language for HarmonyOS with an ARVM backend, stack‑based green threads with dynamic stack growth and a low‑latency moving GC using read barriers that reports pause times usually around 1 ms and rarely over 10 ms. Microbenchmarks show performance comparable to Java. The implementation exposes effect handlers and a restricted form, immediate handlers/resumable exceptions, used to implement FFI coalescing (batching C++ calls), reactive UI dependency tracking and a CSS‑like DSL; these features are implemented and evaluated end‑to‑end.
