React Redux topicks in React js

 React and Redux cover a lot of important concepts that can help you build robust and scalable applications. Here are some key topics to focus on in React and Redux:

React Topics

1. JSX

   • Syntax, embedding expressions, conditionals, lists, etc.

2. Components and Props

   • Function vs. class components
   • Passing props, destructuring props, default props

3. State Management

   • Local state with useState and useReducer
   • Handling forms, conditional rendering based on state

4. Lifecycle and Effects

   • useEffect for side effects
   • Component lifecycle: mount, update, unmount

5. React Context API

   • Creating and providing context
   • Consuming context with useContext

6. React Router

   • Setting up routes with react-router-dom
   • Dynamic routing, nested routes, and redirects

7. Error Boundaries

   • Handling errors in class components using componentDidCatch

8. Performance Optimization

   • React.memo, useCallback, useMemo for memoization
   • Code-splitting with React.lazy and Suspense

9. Refs

   • useRef for accessing DOM elements
   • Persisting state across renders

10. Custom Hooks

    • Creating reusable logic with custom hooks
    • Organizing hooks effectively

Redux Topics

1. Redux Basics

   • Actions, reducers, store
   • Dispatching actions and updating state

2. React-Redux Integration

   • Provider for making Redux store available to the app
   • useSelector and useDispatch hooks for state and actions

3. Redux Toolkit

   • Setting up slices and store with configureStore
   • Creating actions and reducers in slices

4. Async Actions (Redux Thunk)

   • Handling async operations with redux-thunk
   • Dispatching actions in async functions

5. Redux DevTools

   • Setting up and using Redux DevTools for debugging

6. Redux Middleware

   • Writing custom middleware for handling side effects

7. Normalization of State

   • Structuring state to avoid deeply nested data
   • Using libraries like normalizr for complex state

8. Entity Management

   • Managing entities (collections) and pagination
   • Memoizing selectors for efficient state reading

9. Re-select

   • Creating memoized selectors for derived state
   • Avoiding unnecessary re-renders with reselect

10. Testing Redux

    • Testing actions, reducers, and selectors
