Props Typing & Generics for Reusable Components
Type component props clearly and build tiny generic pieces (e.g., List ) using JSDoc or TS. Keep defaults simple and safe.
Why props typing & generics?
Goal: Add clear props types and build a tiny generic component.
- Typed props (title, onClick)
- Defaults via simple fallback
- Generic List<T> that renders any item shape
Key ideas
- Props types: document shape and prevent misuse
- Generics: reuse logic for many data shapes
- Defaults: keep optional values safe
