Modern state management libraries (Redux Toolkit, Zustand) infer store types directly from state definitions.
1. Introduction & Architecture
2. Deep Dive & Core Concepts
Zustand uses state interface generics; Redux Toolkit infers RootState via ReturnType.
3. Basic Code Example
4. Advanced Production Patterns
5. Interactive Code Playground
console.log("Zustand and Redux Toolkit stores typed cleanly.");6. Common Pitfalls & Edge Cases
Note: Use pre-typed custom hooks (
useAppSelector, useAppDispatch) in Redux Toolkit to avoid repeating types in components.7. Interview Q&A & Quizzes
Q: How do you infer RootState in Redux Toolkit?
