Build a Configurable Two-Player Tic-Tac-Toe Board in React

Question

Design and implement a configurable two-player Tic-Tac-Toe board using React, allowing players to customize the game settings.

To build a configurable two-player Tic-Tac-Toe board in React, we need to define the game requirements clearly. The game should allow two players to take turns, display the current state of the board, and determine the winner or if the game ends in a draw. Additionally, we should provide options for players to reset the game and configure board settings, such as size.

The application will consist of several components:
1. **Board**: The main component that renders the grid.
2. **Square**: A component representing each cell in the Tic-Tac-Toe grid.
3. **Game Status**: A component to display the current player's turn and the game outcome.
4. **Controls**: A component for resetting the game and configuring settings.

We will manage the game state using React's `useState` hook to track the board's current state and the active player.

The core logic for the game will involve:
- **Handling Click Events**: When a player clicks on a square, we update the state to reflect the player's move.
- **Winning Logic**: We will implement a function to check for winning combinations after each move.
- **Draw Logic**: If all squares are filled without a winner, we will declare a draw.

Here's a simplified version of how the click handler might look:
```javascript
const handleSquareClick = (index) => {
  if (board[index] || winner) return; // Prevent overwriting or playing after game over
  const newBoard = [...board];
  newBoard[index] = currentPlayer;
  setBoard(newBoard);
  checkWinner(newBoard);
  setCurrentPlayer(currentPlayer === 'X' ? 'O' : 'X');
};
```

While building this application, we should consider scalability and performance. For a simple Tic-Tac-Toe game, the current design is sufficient. However, if we were to expand this to larger grids or add features like an AI opponent, we would need to optimize our state management and possibly introduce more complex algorithms for AI decision-making. We should also think about how to structure our components to keep them reusable and maintainable.
