如何通过模块化简化五子棋游戏中AI下棋逻辑的代码？

// 定义棋盘方向
const directions = [[0, 1], [1, 0], [1, 1], [1, -1]];

// 放置棋子函数
function placePiece(x, y) {
  boxs.value[x][y].place = 2;
  fourDetial = determineEquare3(4, 2, { x, y, place: 2 });
  airPlace.push(x * row.value + y);
}

// 检查并放置棋子函数
function checkAndPlace(x, y) {
  if (boxs.value[x]?.[y]?.place === 0) {
    placePiece(x, y);
    curUser.value = 1;
    return true;
  }
  return false;
}

// 检查并响应四连情况的函数
function handleFourInARow(fourDetial) {
  const { type, geyi, x, y, times } = fourDetial;
  const placement = geyi ?
    (i) => checkAndPlace(i, y) :
    ([dx, dy]) => checkAndPlace(x + dx * times, y + dy * times);

  if (geyi) {
    for (let i = x; i > x - times + 1; i--) {
      if (placement(i)) return;
    }
  } else {
    for (const direction of directions) {
      if (placement(direction)) return;
    }
  }
}


// 优化后的airPoint函数
function airPoint() {
  // 检查是否有四连
  if (!isEmptyObject(fourDetial)) {
    handleFourInARow(fourDetial);
    return;
  }

  // 检查是否有阻挡用户的棋型
  const blockingMove = determineEquare3();
  if (blockingMove) {
    handleFourInARow(blockingMove);
    return;
  }

  // 尝试五连
  airFiveLine();

  curUser.value = 1;
}
