Completely new kernel and userspace? Wonder how long until it's Tier 1 or Tier 2 for Rust. ... Do they use GCC in China?

It's already Tier 2. [1]

*-unknown-linux-ohos:

> Tier: 2 (with Host Tools): aarch64-unknown-linux-ohos, armv7-unknown-linux-ohos, x86_64-unknown-linux-ohos

> Tier: 3: loongarch64-unknown-linux-ohos

OpenHarmony has no support for gcc. All the toolchains are LLVM. [2]

I find it interesting not only that HarmonyOS is using a microkernel but also that its userland application language is compiled TypeScript.

I'd certainly be interested in benchmarks of running TypeScript via ArkTS vs transpiled JS in in V8.

ArkTS compiles into Ark Bytecode, and there is JIT on the user's device. According to feedback from the developer community, ArkTS is slower than V8, but Huawei has incorporated a multi-threading model into it.
