#description

React is an open-source JavaScript library that is used for building user interfaces (UI) for web applications. To get started with React, the first step is to install it on your computer.

Here are the steps to install React:
  1. Install Node.js: React requires Node.js, which is a server-side JavaScript runtime environment, to be installed on your computer. You can download and install Node.js from the official website: https://nodejs.org/en/download/
  1. Create a new React project: Once Node.js is installed, you can use the create-react-app command-line tool to create a new React project.

Open your terminal or command prompt and run the following command:

 
                    
    npx create-react-app my-app

This command will create a new React project in a directory named my-app.

  1. Run the React project: Once the project is created, you can navigate to the project directory and start the development server by running the following commands:
 
                    
    cd my-app
    npm start

This will start the development server and open the React project in your default web browser.

That's it! You have now installed React and created a new React project. You can now start building your own React components and UI for your web application.
