Summary
Microsoft released TypeScript 7.0, a native Go port delivering 8-12x faster builds and lower memory usage (e.g., VS Code build drops from 125.7s to 10.6s, memory from 5.2GB to 4.2GB). The rewrite maintains full API compatibility while enabling shared-memory multithreading and LSP support for editors like VS Code and WebStorm. Initial file-error detection in large codebases improved from 17.5s to under 1.3s.
