TicTacToe - should the winner be part of the model?

Learn

This was a fun kata! I opted for using Array as I never used it before.

type alias Model =
    { board : Board
    , currentPlayer : Player
    }


type Player
    = Blank
    | X
    | O


type alias Board =
    { rows : Array (Array Player)
    }


initBoard : Board
initBoard =
    { rows = Array.repeat 3 (Array.repeat 3 Blank)
    }

However, an Array of Arrays is not straightforward to update:

updateBoard : Board -> Int -> Int -> Player -> Board
updateBoard board x y p =
    let
        newRow =
            case Array.get y board.rows of
                Just aRow ->
                    Array.set x p aRow

                Nothing ->
                    Array.repeat 3 Blank
    in
    { board | rows = Array.set y newRow board.rows }

Sorry for being OT but I just got feeling. :slight_smile:
