⚡ Announcing TypeScript 7.0 RC

Big milestone: the compiler has been ported from TypeScript/JavaScript to Go, delivering ~10x faster build times compared to v6.0.

🔑 Highlights
Native code speed + shared-memory parallelism

New flags: --checkers & --builders for fine-tuned parallel builds

Rebuilt --watch mode (Go port of Parcel’s watcher)

New defaults: strict: true, module: esnext

Deprecated flags → now hard errors

Compatibility package: @typescript/typescript6 for side-by-side installs

VS Code TypeScript Native Preview extension brings performance gains to the editor (auto-imports, inlay hints, semantic highlighting, etc.)

💡 A stable release is planned within the next month, with a programmatic API coming in TypeScript 7.1.

👉 This is a huge step forward for developer productivity and DX.
