Summary
TypeScript 7.0 (July 8, 2026) rewrites the compiler in Go, achieving 10x speedups (e.g., VS Code from 125.7s to 10.6s) via native compilation and shared-memory multithreading with 4 default workers (up to 16.7x with 8). Editor project load drops from 9.6s to 1.2s, and aggregate build memory decreases 18-26%. The runtime remains unchanged—.ts files still compile to .js.
