TypeScript Native Compiler: 10x Performance Boost
2025-03-11
The TypeScript team announced a native port of the TypeScript compiler and tools to dramatically improve performance. This native implementation is projected to drastically speed up editor startup, reduce most build times by 10x, and substantially reduce memory usage. Initial testing shows compilation speed improvements of more than 10x for several large projects (e.g., VS Code, Playwright). Future native TypeScript (planned as TypeScript 7) will support more advanced refactorings, deeper code analysis, and lay the foundation for next-gen AI development tools. TypeScript 6 (JS-based) will continue to be maintained to ensure a smooth transition.
