How do you create a React app?

To create a React app, you need to have Node.js installed on your computer. Once you have Node.js installed, you can use the Node Package Manager (npm) to install the create-react-app package globally by running the following command in your terminal:

npm install -g create-react-app

After installing create-react-app, you can create a new React app by running the following command in your terminal:

create-react-app my-app

This will create a new directory called my-app in your current directory with all the necessary files and dependencies to start building a React app. You can then navigate into the my-app directory and start the development server by running the following command:

cd my-app
npm start

This will start the development server and open your app in a new browser window. You can then start building your React app by editing the files in the src directory and seeing the changes live in your browser.
