Great libraries have types that guide the developer. Here is how to write TypeScript that feels like magic.
Why Generics Matter
Generics allow your components to accept data of various shapes while still guaranteeing type safety. It's the difference between any and precise, autocompleted code.
Inferred Types
The real power comes when you let TS infer the type from the argument.
function createHandler<T>(data: T): { payload: T } { ... }Conditional Types
Using T extends U ? X : Y allows you to create types that change based on inputs. This is crucial for things like polymorphic components (e.g. a Button that acts like an <a> tag if an href is passed).
