| description.long | A type analysis tool for Python that enables code to transition from pure dynamic typing to statically-typed code through annotations, with error detection at check time. Code runs with negligible performance impact and developers can incrementally adopt static types in existing projects. | An open-source toolkit providing linting, formatting, parsing, transformation, module resolution, and minification for JavaScript and TypeScript through Rust implementation, achieving significantly higher performance than comparable tools. |
