How to create react app?

To create a React app, you'll need to have Node.js and npm (Node Package Manager) installed on your computer. Once you have these prerequisites installed, you can follow these steps to create a new React app:

1. Open a terminal window or command prompt.
2. Install the create-react-app package globally by running the following command:

npm install -g create-react-app         

1. Once the installation is complete, navigate to the directory where you want to create your React app.
2. Run the following command to create a new React app:

npx create-react-app my-app         

Replace my-app with the name you want to give to your app.

1. Once the command completes, navigate to the app directory:

cd my-app         

1. Finally, start the development server by running:

npm start         

This will start the app and open it in your default browser. You can now start building your React app by modifying the source files in the src directory. Any changes you make to these files will be automatically updated in the browser.
