2. Why React.js? React.js has gained immense popularity due to its component-based architecture, efficient performance, and large, active community. It's widely used for building user interfaces for web and mobile applications. Component-Based Architecture Virtual DOM 1 2 React's Virtual DOM efficiently updates only the necessary parts of the UI, resulting in improved performance and responsiveness. React.js allows you to break down complex UIs into reusable, independent components, simplifying development and maintenance. JSX Large Ecosystem 3 4 JSX, a syntax extension, allows you to write HTML- like code within your JavaScript, enhancing code readability and maintainability. React.js boasts a vast ecosystem of libraries and tools, providing extensive support for various development needs.

3. React.js Fundamentals This module covers the essential concepts of React.js, laying the foundation for building robust and interactive applications. You'll learn about JSX, components, props, state, and lifecycle methods. JSX 1 JSX is a syntax extension that allows you to write HTML-like code within your JavaScript. It enhances code readability and maintainability. Components 2 React applications are built using components, which are reusable building blocks that encapsulate specific UI elements and functionality. Props 3 Props are used to pass data from parent components to child components, enabling data flow and communication between components. State 4 State manages data that changes within a component over time, allowing you to dynamically update the UI based on user interactions or other events. Lifecycle Methods 5 Lifecycle methods are functions that are automatically called at different stages of a component's lifecycle, enabling you to perform specific actions at different points.

4. React.js Components Components are the core building blocks of React applications. Learn about functional and class components, how to create reusable UI elements, and pass data between components using props. Functional Components Class Components Props and State Functional components are pure functions that receive props as input and return JSX. They are stateless and ideal for simple UI elements. Class components are more complex, allowing you to manage state and lifecycle methods. They are suitable for components with complex logic and interactions. Props are immutable data passed from parent to child components, while state is mutable data managed within a component. Understanding how to use props and state is crucial for building dynamic UIs.

5. State Management in React.js Learn different approaches for managing state in React applications, from using component state to employing libraries like Redux for complex applications. Component State Context API Redux The simplest form of state management, where state is managed directly within a component using the `useState` hook. Provides a way to share state across multiple components without explicitly passing it down through props. It's useful for sharing global data. A powerful library for managing complex state, providing centralized state management, predictable updates, and improved developer tooling.

6. Routing in React.js React Router is a popular library for implementing navigation and routing in React applications. It allows you to define different routes for various pages and handle transitions between them. Route Definition Define different routes for different pages or views within your application using the `BrowserRouter` and `Routes` components. 1 Route Matching React Router automatically matches the current URL with your defined routes, rendering the corresponding component. 2 Navigation 3 Use the `Link` component to create links that navigate between routes, providing a seamless user experience.

7. React.js Hooks React hooks are functions that allow you to access React features like state, lifecycle methods, and context without writing class components. They simplify your code and make it more readable. Hook Description useState Manages component state. useEffect Performs side effects, like fetching data or setting up subscriptions. useContext Accesses values from the context API. useReducer Manages complex state with a reducer function.
