Build the classic game Connect Four using JavaScript and React.js.

• Built using React
• Use only functional, stateless components. Components should only render based on their props. Components should not have any state.
• There should be "one source of truth" for the game's state. ie: one state object
• You should be able to start a game, play to completion, and then begin a new game, etc. ie: it never "stops"
• The application should detect when a game has been won or ends in a draw.
• Players should be able to enter their names and have them displayed on the screen.
• The game should work well on a mobile device. Imagine two friends passing a phone back and forth while waiting in line for a concert or similar.
• Use plentiful console.assert() statements to unit test your game logic code.
• Put all game logic code into it's own module.

• Keep a running scoreboard of wins / loses.
• Players should not lose their game state when the browser is refreshed.
  • Hint: use localStorage + JSON
• Record a history of the games. Be able to "play back" old games.
