Generics let you express intent without sacrificing type safety. Start with simple identity functions and widen to constraints (`<T extends object>`) to shape acceptable inputs.
Use utility types (`Partial`, `Pick`, `Omit`) alongside generics to build flexible APIs. Prefer inference over explicit annotations so consumers write less boilerplate.
Validate your designs with real-world usage: if generics feel unwieldy, consider narrowing the API or offering overloads to guide callers.
