To start the game, clone the repo and open up the terminal.
node src/tictactoe.js to start the game.
The tic-tac-toe squares are numbered one through nine, starting from the top left ("one") to the bottom right ("nine"). When prompted, enter a valid square to toggle the square. Use the word rather than the number to identify the square (e.g. "one", "five", "nine"; not 1, 5, 9).
The loser buys the winner ice cream. No ifs ands or buts.
