TypeScript with React

React and TypeScript are the dominant pairing in modern frontend development, and using them well means knowing how to type components, props, state, hooks, events, and refs so the compiler guards your UI as thoroughly as it guards the rest of your code. This matters because UI bugs — passing the wrong prop, forgetting a required one, mishandling an event, rendering data that has not loaded — are among the most common and most user-visible, and TypeScript catches the entire class of them at compile time when components are typed properly. A typed component is a self-documenting contract: its props interface tells every consumer exactly what to pass, autocomplete surfaces the options, and a missing or mistyped prop fails to compile. The integration is largely about applying the type tools you already know — interfaces, generics, unions, utility types — to React's specific shapes. Getting it right turns React from a place where props and state are loosely-typed guesses into one where the component boundary is a checked contract, which is exactly what keeps large component trees maintainable.
