Performance
TypeScript compiles to JavaScript with no runtime overhead. Use incremental compilation, project references, and proper tsconfig for faster builds.
Security
Type safety helps prevent runtime errors but doesn't replace runtime validation. Use Zod or similar for runtime type checking at system boundaries.
Scaling
TypeScript becomes more valuable as codebases grow. Consider project references for large monorepos to optimize build times.

Implementation Considerations
