Create new react app

To create a new React app, you can use the create-react-app command-line tool. Here are the steps:

Step 1: Install create-react-app

Open your terminal and run the following command:

npm install -g create-react-app

This will install create-react-app globally on your system.

Step 2: Create a new React app

Once installed, run the following command to create a new React app:

npx create-react-app my-app

Replace my-app with the name of your app.

Step 3: Navigate to the app directory

After creating the app, navigate to the directory using the following command:

cd my-app

Step 4: Start the app

To start the app, run the following command:

npm start

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

Step 5: Explore the app

You can now explore the app by navigating to the src directory, which contains the React code. You can also modify the code and see the changes reflected in the browser.

That's it! You now have a brand new React app up and running.

Here's a breakdown of the files and directories created by create-react-app:
