TypeScript Type Utils

typescript-type-utils is a lightweight, zero-runtime collection of TypeScript utility types designed to enhance type safety and enable advanced type manipulations within projects. At version 0.1.0, it provides a set of 'test-kit' types for compile-time API signature verification (e.g., `ExpectTrue`, `Equal`) and 'tuple-utils' for advanced tuple type transformations (e.g., `TupleToUnion`, `ReduceTupleOn`). A key differentiator is its strict design principle: the package explicitly contains only `.d.ts` declaration files, meaning it ships no actual JavaScript code, thereby ensuring zero runtime footprint and no potential for runtime errors. Its release cadence is likely infrequent given its stable, pure-type nature and early version number, focusing on robust and broadly applicable type definitions rather than rapid feature additions.
