To learn React.js from scratch, follow these steps:

  1. Familiarize yourself with HTML, CSS, and JavaScript: React.js is a JavaScript library, so having a solid understanding of JavaScript fundamentals is essential. Also, having a basic understanding of HTML and CSS will help you in building React components.
  2. Set up your development environment: Install Node.js and npm (Node Package Manager) on your computer. This will allow you to create and manage React projects. You can download Node.js from the official website (https://nodejs.org/) or use a package manager like Homebrew on macOS or Chocolatey on Windows.
  3. Learn the basics of React.js: Start by going through the official React.js documentation (https://reactjs.org/docs/getting-started.html). This will give you an overview of React's core concepts and how it works. You can also find tutorials and online courses to learn React.js from resources like Udemy, freeCodeCamp, Codecademy, and YouTube.
  4. Build simple React components: Practice building simple React components like buttons, forms, or navigation bars. Start with a simple project structure and gradually increase the complexity as you gain more confidence.
  5. Understand React's component lifecycle: React components have lifecycle methods that get called at different stages of their lifecycle. Familiarize yourself with these methods, such as componentDidMount, componentDidUpdate, and componentWillUnmount, as they allow you to manage component state and perform actions at specific points in the component's life.
  6. Learn about state and props: State and props are key concepts in React.js. Understand how to manage state within a component and how to pass data to child components using props.
  7. Practice with React Router: React Router is a popular library for handling routing in React applications. Learn how to use it to create and manage routes in your applications.
  8. Dive deeper into advanced concepts: Once you have a good grasp of the basics, explore more advanced topics such as React Hooks, React Context API, Redux (a popular state management library), and styling options like CSS-in-JS with libraries like styled-components or CSS modules.
  9. Build real-world projects: To solidify your understanding of React.js, work on building real-world projects. This will provide hands-on experience and help you understand how to structure and architect larger React applications.
  10. Join the React community: Engage with the React community by joining online forums, attending meetups, or joining communities on platforms like Discord or Slack. This will provide opportunities to ask questions, contribute to open-source projects, and learn from experienced developers.


Remember, learning React.js is an ongoing process, and it's important to keep practicing and building projects to deepen your understanding.
