Rust Port of TypeScript (Tsc)

A developer used large language models to port the TypeScript compiler from Go to Rust, achieving a working version (ts-rust) that claims 100% compatibility with real-world projects. The project cost approximately $24,000 in API tokens using Claude Opus 5.5, which completed the port in roughly 10 hours—significantly faster and cheaper than previous attempts with other models that spent over $400,000 with only 84% compatibility.
