Stujo's Tic Tac Toe

Is it possible to create an unbeatable Tic Tac Toe agent which doesn't enumerate all the cases?

I'm sure it is, and this is my attempt

• There are three ways to play with this code
  • Just the Agent (as a node module dependency)
  • Using the whole App
  • Via the deployed API

Just the Agent

$ mkdir ttt-client
$ cd ttt-client
$ npm init 
# Complete the init

Install the tictactoe-agent

$ npm install tictactoe-agent --save

Add: index.js

var TicTacToe = require('tictactoe-agent');

var model = new TicTacToe.Model('---------', 'X');

var recommendation = model.getRecommendation();

console.log(recommendation.index);

// Will Print out the recommended move

Using the Whole App

tictactoe is a command line node.js application which takes the game state and current player 'X' or 'O' as parameters as follows:

$ git clone [email protected]:stujo/javascript-node-tic-tac-toe.git
$ cd javascript-node-tic-tac-toe
$ ./tictactoe --------- x
********************************************************
#####
#   #
#   #
#   #
#####
********************************************************
* Recommendation for X is 2 (Score: 3)
********************************************************

The board state is provided as a string with hyphens denoting empty spots, and X or O marking the take spots

The spots on the board are numbered as follows:

#####
#012#
#345#
#678#
#####

The optional fourth parameter debug prints out debugging info:

$ ./tictactoe --------- x debug
