- Check Node is up to date

1. Check Node is up to date
Go to https://nodejs.org/en/

The left button shows the latest stable version of Node. In this case, it’s 12.18.1
Check your Node version in Terminal with this command:
node --version
Make sure your version is the latest stable version.
2. Install VSCode
You don’t have to use VSCode as your code editor, but many recommend it because it has a lot of extensions that make it really easy to work with React.
Go to https://code.visualstudio.com. Download for Mac

3. Create React app
In Terminal:
npx create-react-app my-app
If that doesn’t work, install with npm or yarn:
npm init react-app my-app
yarn create react-app my-app
4. Run app
cd my-app
npm start or yarn start
