tsc-ts: TypeScript written in TypeScript
Developers have introduced tsc‑ts, a reimplementation of the TypeScript compiler written entirely in TypeScript. The project aims to make the compiler more maintainable by using the language it compiles, allowing developers to apply TypeScript’s type‑checking and tooling to its own codebase. The initiative was posted on Hacker News, where the community discussed potential benefits and challenges of this self‑hosting approach.
