   • Learn how to initialize and update state using setState.
   • Explore the use of state to build interactive and dynamic user interfaces.
4. Lifecycle Methods:
   • Gain a comprehensive understanding of React’s component lifecycle and the different phases it goes through.
   • Learn how to leverage lifecycle methods to perform specific actions at various stages of a component’s lifecycle.
   • Understand the deprecation of certain lifecycle methods in newer versions of React.
5. Virtual DOM:
   • Understand the concept of the Virtual DOM and its role in optimizing React’s rendering process.
   • Learn how React’s reconciliation algorithm works to efficiently update the DOM.
   • Explore the benefits of using the Virtual DOM in terms of performance and user experience.
6. React Router:
   • Learn how to set up routing in a React application using React Router.
   • Understand how to define routes, handle navigation, and create nested routes.
   • Explore advanced features of React Router, such as route parameters and route guards.
7. Hooks:
   • Understand the motivation behind React Hooks and their benefits.
   • Learn how to use built-in hooks like useState, useEffect, and useContext.
   • Explore custom hook creation and how to leverage hooks to write more concise and reusable code.
8. Context API:
   • Understand the Context API and how it enables global state management in React applications.
   • Learn how to create and consume context using the createContext and useContext hooks.
   • Explore advanced usage patterns of the Context API, such as nested contexts and context composition.
9. Redux:
   • Gain a thorough understanding of Redux and its core principles.
   • Learn how to set up Redux in a React application and manage global state.
   • Explore concepts such as actions, reducers, and the Redux store, and understand how they work together.
10. Higher-Order Components (HOCs):
    • Understand the concept of Higher-Order Components and their role in code reuse and composition.
    • Learn how to create and use HOCs to add additional functionality to React components.
    • Explore common use cases for HOCs, such as authentication and authorization.
11. Render:
    • Understand the rendering process in React and how components are rendered to the DOM.
    • Learn about conditional rendering techniques based on state and props.
    • Explore performance optimizations related to rendering, such as shouldComponentUpdate and React.memo.
12. Reconciliation:
    • Gain a deep understanding of React’s reconciliation process and how it determines what needs to be updated in the DOM.
    • Learn about the diffing algorithm and how React efficiently updates the UI by comparing the previous and current Virtual DOM trees.
    • Understand strategies for optimizing reconciliation, such as using unique keys and minimizing component updates.
13. Unidirectional Data Flow:
    • Understand the concept of unidirectional data flow in React and its advantages.
    • Learn how to design React applications using a single source of truth for data.
    • Explore patterns such as state lifting and data sharing between components.
14. Synthetic Events:
    • Understand the concept of synthetic events in React and how they differ from native browser events.
    • Learn how to handle and respond to events in React components.
    • Explore common event handling patterns and techniques.
15. Event Handling:
    • Learn how to handle different types of events in React components, such as onClick, onChange, and onSubmit.
    • Understand how to write event handlers and update state or trigger actions based on user interactions.
    • Explore advanced event handling techniques, such as event delegation and event bubbling.
