⚡ Announcing TypeScript 7.0

Big milestone: TypeScript has officially been ported to Go, delivering 8x–12x faster build times and dramatically reduced memory usage.

🔑 Highlights
🚀 Performance Gains → VS Code’s build time dropped from 125.7s → 10.6s, editor load time from 17.5s → 1.3s.

🧩 Parallel Type-Checking → New --checkers & --builders flags for fine-tuned parallel builds.

👀 Rebuilt Watch Mode → Powered by a Go port of Parcel’s file watcher, efficient across platforms.

🛠️ Editor Support → Full LSP-based integration for VS Code with auto-imports, inlay hints, semantic highlighting.

📦 Defaults & Cleanup → Stricter defaults (strict: true, module: esnext) and removal of legacy options (target: es5, baseUrl, AMD/UMD).

🔄 Compatibility Package → @typescript/typescript6 for side-by-side installs where the old programmatic API is still needed.

⏳ Future → Embedded frameworks (Vue, Svelte, Astro, Angular) will gain support with the programmatic API in TypeScript 7.1.

💡 Takeaway: TypeScript 7.0 isn’t just faster — it’s a reimagined compiler that sets the stage for the next decade of developer productivity.
