    What does it do?

    tictactoe-minimax-ai provides an api for computing the best move for a computer to play in a game of tictactoe.

    Methods:

    bestMove(gameBoard /2d matrix representing the current game state of the board/, options)

    Returns the position that has the highest chance of winning (See figures under ## Examples)
    Note: By default, computer is x and player is o. Empty positions are represented by the character _ (underscore).

    The argument options should be an object containing the following:

    • computer: the character used to represent the computer
    • opponent: the character used to represent to opponent / player
    Example:
    const tictactoe = require('tictactoe-minimax-ai');
     
    let options = {
        "computer": "o",
        "opponent": "x"
    };
     
    console.log(tictactoe.bestMove(data, options));

    This sets the character that represents the computer to "o" and the one for the player to "x".

    Note: By default, computer is always "x" and player is always "o".

    boardEvaluate(gameBoard /same as previous/)

    Returns the current state of the game. Possible return values:

    • "win" (for computer)
    • "loss"
    • "tie"
    • "none"

    The structure of the return value is an object with a data member "status".

    Examples:

    const tictactoe = require('tictactoe-minimax-ai');
    // array representation of the game board
    let data = [
        ['o','_','_'],
        ['_','x','_'],
        ['_','_','_']];
     
    let options = {
        "computer": "o",
        "opponent" "x"
    };
     
    console.log(tictactoe.bestMove(data, options)); // prints out lcation for best move
     
    console.log(tictactoe.boardEvaluate(data)); // returns either "tie", "win", "loss", "none". Expected "none"

    console.log(tictactoe.bestMove(data)); logs 8 in the console because tictactoe.bestMove() returns the best location for the computer if the scenario was:

    O _ _
    _ X _
    _ _ _

    The 8 represents the bottom right position. More return options will be added in futur versions.

    console.log(tictactoe.boardEvaluate(options)); logs:

    {
        "status": "none"
    }

    because the game still hasn't finished.
