That’s right. The new TypeScript compiler is being rewritten in Go — and it’s blazing fast.

In my latest post, I cover everything you need to know about this bold move by the TypeScript team:

  • 🧠 Why Go was chosen as the new foundation
  • 🚀 How they achieved 10x speed and 50% lower memory usage
  • 🧵 What it means for developers, build tools & IDEs
  • 🧪 How concurrency in Go unlocks massive performance gains
  • 🔧 What's next: public compiler API, LSP support & plugin systems

👉 Read the full breakdown (with compiler internals + what’s coming):

💡 Whether you’re building large-scale apps, maintaining a TS codebase, or just obsessed with compilers — this shift could seriously improve your daily workflow.
Bonus: it’s all being done with maximum backward compatibility in mind. Smooth migration, fast builds, fewer memory crashes — what’s not to love?
