This effort (codenamed “Project Corsa”, and soon “TypeScript 7.0”) has been a significant undertaking, but we’ve made big strides in the past few months. We’re […]The post Progress on TypeScript 7 – December 2025 appeared first on TypeScript.

This past March we unveiled our efforts to port the TypeScript compiler and toolset to native code. This port has achieved a 10x speed-up on most projects – not just by using a natively-compiled language (Go), but also through using shared memory parallelism and concurrency where we can benefit. Since then, we have made several […]The post Announcing TypeScript Native Previews appeared first on TypeScript.
