How is Redux different from React's internal state management?

While both Redux and React manage state, they do it in very different ways:

FeatureReact Internal State (useState, useReducer)Redux
ScopeComponent-level stateApplication-wide state
Data FlowLocal to component or manually liftedCentralized and flows in one direction
Update MechanismDirectly with setter functionsOnly through actions and reducers
Complexity HandlingGood for small/medium appsBetter for large, complex apps
Debugging ToolsBasicPowerful tools like Redux DevTools
BoilerplateMinimalMore (but less with Redux Toolkit)

In simple terms:
React’s state is great for local component state, but for large-scale data sharing across the app, Redux is the better choice.
