Init a new react application. There is multiple ways how to work with react, but we will be using "CREATE REACT APP" toolchain. Read what it does here

• Run command npx create-react-app my-app
• This command will run for a while. (PRO tip: Windows - if you feel funky, you can pause your anti-virus which will speed up things. Linux/Mac users are fine)

Verify that the application is correctly installed by running the commands

• cd my-app enter the correct folder
• npm start which will start a local development server which does automatic rebuilds of your app when you change files

Edit App.js and observe the changes in your browser

Edit a return on function app in app.js to say:

• Remove the <header>, your return should look like this:

  return (
    <div className="App">
     //.. your new code
    </div>
  );
  

• Hello wrapped in h1 element
• From the React world! as h2 element
• 

Move the h2 element with text From the React world! into variable. As per variable declaration

• Use this variable inside your return function using {myVariable} on the place where h2 element was previously created.
• The rendered output should stay the same!
