Before jumping into Redux, you must master the built-in way to handle complex state. useReducer provides predictable state transitions, and Context API removes "Prop Drilling" (passing data through 5 components that don't need it).
Instead of 10 different useState calls, use a Reducer. It centralizes your logic into a single function that handles "Actions." This is much easier to unit test and debug.
Context allows a "Provider" to broadcast data to any "Consumer" in the tree, no matter how deep. Architect Tip: Don't put everything in one giant Global Context. This causes the entire app to re-render whenever *one* tiny value changes. Use multiple "Feature-Level" contexts for better performance.
Q: "Is Context API a replacement for Redux?"
Architect Answer: "No. Context is a **Transport** mechanism (dependency injection), not a state management system. Unlike Redux, Context doesn't have advanced features like 'Time Travel Debugging,' 'Middleware,' or 'Selective Subscriptions.' In a simple app, Context is enough. In a massive enterprise app with 50+ developers, the structure and tooling of Redux or Zustand are indispensable."
