Announcing TypeScript 7.0 Beta

SMRTR summary

TypeScript 7.0 Beta is here, and it's a massive leap: the entire compiler has been ported from TypeScript/JavaScript to Go, delivering roughly 10x faster build times through native code and shared-memory parallelism. The type-checking logic is structurally identical to 6.0, so compatibility is high. Install via npm as @typescript/native-preview and run tsgo today.
