Contributions summary:Quanlin primarily contributed to defining and refining type definitions for the Ramda and Axios libraries within the flow-typed repository. Their work involved updating function signatures to accept read-only array inputs, implementing new definitions for functions like `uniq`, `adjust`, `chain`, and `nth`, and refactoring existing definitions, specifically related to `intersection` and options for `axios`. These changes improve the type safety and usability of these libraries within Flow-typed projects.
