React JS Training

React JS is one of the most powerful JavaScript libraries for building dynamic, high-performance, and scalable user interfaces. This course provides an in-depth understanding of React, taking you from the fundamentals to advanced concepts. By the end of the course, you will be equipped to develop real-world web applications and will have a solid grasp of React's features like hooks, state management, routing, and optimization techniques.

Introduction to React

What is React and why it is used?
Setting up a React development environment using Create React App.
Understanding JSX and the Virtual DOM.
Creating and rendering components in React.

React Components and Props

Components: Creating functional and class-based components.
Props: Passing data to components using props.
Component Reusability: Designing modular components.
Understanding and handling component hierarchy.

State Management with React

useState: Managing state in functional components.
State Propagation: Passing state between parent and child components.
useEffect: Handling side effects such as fetching data.
State management in class components using `this.state`.

Handling Events in React

Understanding event handling in React.

Passing parameters and query strings with React Router.
Handling nested routes and redirects.

Advanced React Concepts

React Hooks: useContext, useReducer, and creating custom hooks.
Context API: Managing global state without prop drilling.
Higher-Order Components (HOCs): Reusing logic in components.
Error boundaries and lazy loading components for performance.

React State Management with Redux

Introduction to Redux for managing global state.
Understanding actions, reducers, and the store.
Connecting React with Redux using React-Redux.
Working with middleware in Redux (e.g., Redux Thunk for async operations).

React Performance Optimization

Memoization: Using `React.memo`, `useMemo`, and `useCallback` to prevent unnecessary re-renders.
Code splitting and lazy loading for faster load times.
Optimizing React rendering with key attributes and `shouldComponentUpdate`.
Using the React DevTools for performance profiling.

Writing unit tests for React components.
Simulating events and testing user interactions.
End-to-end testing using Cypress for React apps.

Deploying React Applications

Building and bundling React apps for production.
