Port of the TypeScript compiler, checker and lsp to Rust, by LLM

What happened: A developer used LLMs to port Microsoft's native TypeScript compiler, checker and language server to Rust, released as tsc-rs on npm. The author states he has never read the code and calls it an early release. Key numbers: Over $400,000 in API tokens spent with OpenAI models, which reached about 84% compatibility. Why it matters: The author reports 100% compatibility on real world projects tested and says type checking takes about half of Go's time on 60 open-source projects. He warns he does not know if it will actually work.
