2. Type the following command and press Enter:lua

npx create-react-app my-app

Replace “my-app” with the name of your app.

Wait for the tool to finish setting up the new React app. This may take a few minutes.

Once the tool has finished setting up the app, navigate into the app directory by typing the following command and pressing Enter:

bash

cd my-app

Replace “my-app” with the name of your app.

To start the development server and launch the app, type the following command and press Enter:
