About this course
React, often referred to as React.js or ReactJS, is an open-source JavaScript library developed by Facebook. It is mainly used for building user interfaces (UIs) for web applications. React focuses on creating UI components that can efficiently update and render in response to changes in data, making it a powerful tool for building dynamic and interactive web applications.
1. React Basics:
- Understand the core concepts of React, including components, JSX (JavaScript XML), props, and state.
- Learn how to create functional and class components and the difference between them.
- Gain familiarity with rendering components using ReactDOM.render().
2. Component Lifecycle:
- Study the component lifecycle methods, including componentDidMount, componentDidUpdate, and componentWillUnmount.
- Learn about the new lifecycle methods introduced with React 16.3+ and hooks like useState, useEffect, and useContext.
3. State Management:
- Explore how to manage component state using the useState hook or class component state.
- Understand the difference between props and state and when to use each.
- Learn about state lifting, controlled components, and uncontrolled components.
4. Conditional Rendering:
- Learn how to conditionally render components and content using if statements and the ternary operator.
- Understand how to use logical operators like && and the ternary operator for inline conditional rendering.
5. Lists and Keys:
- Explore how to render lists of data using the map() function and provide unique keys to improve rendering performance.
- Understand the importance of keys in helping React identify which items have changed in a list.
6. Forms and User Input:
- Learn how to create controlled forms, handle user input, and manage form state.
- Explore form elements such as input fields, checkboxes, radio buttons, and select elements.
7. Styling and CSS-in-JS:
- Understand different approaches to styling React components, including using CSS, CSS modules, and CSS-in-JS libraries like styled-components or Emotion.
8. React Router:
- Study React Router to enable navigation and routing in single-page applications (SPAs).
- Learn how to set up routes, nested routes, route parameters, and navigation links.
9. State Management Libraries:
- Explore state management libraries like Redux or MobX for managing global application state.
- Understand the concepts of actions, reducers, and stores in Redux.
10. Component Composition:
- Learn how to compose components and break down complex UI into smaller, reusable components.
- Understand the concept of component composition and how it contributes to maintainable code.
11. Context API:
- Explore React's Context API for managing global state and sharing data across components without prop drilling.
12. Hooks:
- Study hooks like useState, useEffect, useContext, useReducer, and custom hooks.
- Understand how hooks simplify component logic and improve code organization.
13. Error Handling and Debugging:
- Learn how to handle errors gracefully using try...catch blocks and error boundaries.
- Understand tools like React DevTools for debugging and inspecting components.
14. Server-side Rendering (SSR) and Static Site Generation (SSG):
- Gain an understanding of server-side rendering and static site generation using tools like Next.js.
15. Performance Optimization:
- Explore techniques for optimizing React application performance, including lazy loading, memoization, and code splitting.
16. Testing:
- Learn about testing methodologies for React components, including unit testing and integration testing using tools like Jest and React Testing Library.
