State management in React refers to the process of handling and sharing data (state) across components to ensure a consistent UI. React has built-in state mechanisms: local state managed via use State or use Reducer, and component re-renders occur when state changes.

For simple or isolated state (like toggling UI elements or form inputs), local state is sufficient. But as your application grows and components need to share state, prop drilling—passing data through many layers—becomes inefficient.

To handle shared or global state, tools like the Context API and Redux come in.

Context API is best for light global state (e.g., user authentication, theme settings). It avoids prop drilling by providing a way to pass data through the component tree. However, it isn’t optimized for frequent state updates, as re-renders can affect all consumers.

Redux is a powerful state container suited for large-scale applications with complex state logic and frequent updates. It uses a centralized store, pure reducer functions, and middleware for handling side effects (e.g., API calls). Redux can feel verbose, but modern tools like Redux Toolkit simplify setup and reduce boilerplate.

Use Context when:

You have low-frequency global state.

The app is small to medium-sized.

Use Redux when:

State logic is complex or shared across many components.

You need advanced features like time-travel debugging, middleware, or dev tools.

In summary, start with React’s built-in tools, use Context for small global needs, and adopt Redux when scaling demands it.
