Before Coding Dojo

1. Make sure you have a recent version of Node.js installed.

2. Create a skeleton for tic-tac-toe app:

   • npm install -g create-react-app
   • create-react-app tic-tac-toe
   • cd tic-tac-toe
   • yarn start
   • Delete all files in the src/ folder
   • Add a file named index.css in the src/ folder with this CSS code
   • Add a file named index.js in the src/ folder with this JS code, and then add three lines to the top of it:

   import React from 'react';
   import ReactDOM from 'react-dom';
   import './index.css';
