我有一款小型井字游戏，一切都很好，只是我在代码中苦苦寻找将完成函数放在哪里。让我告诉你；

import React, { useState } from "react";
import { isGameOver } from "../Helper/helper";
import Square from "./Square";

const Board: React.FC = () => {
  const [squares, setSquares] = useState(new Array(9).fill(""));
  const [activePlayer, setActivePlayer] = useState("Player 1");
  const [winner, setWinner] = useState<any>();

  const clickSquare = (id: number): void => {
    if (!squares[id]) {
      if (activePlayer === "Player 1") {
        setActivePlayer("Player 2");
      } else {
        setActivePlayer("Player 1");
      }
    }
    setSquares((prevSquares) => {
      return prevSquares.map((square, i) => {
        if (i === id && !square) {
          square = activePlayer === "Player 1" ? "X" : "O";
        }
        return square;
      });
    });
  };

  return (
    <div className="board">
      <div className="game-field">
        {squares.map((square, i) => {
          return (
            <Square clickSquare={clickSquare} square={square} key={i} i={i} />
          );
        })}
      </div>
      <p
        style={{
          marginRight: activePlayer === "Player 1" ? "250px" : "-250px",
        }}
      >
        {activePlayer + "'s turn"}
      </p>
      <p> </p>
    </div>
  );
};

export default Board;

这基本上就是整个游戏，我在另一个文件中有一个完成函数，如下所示；

export const isGameOver = (squares: String[]) => {
  const won = [
    [0, 1, 2],
    [3, 4, 5],
    [6, 7, 8],
    [0, 3, 6],
    [1, 4, 7],
    [2, 5, 8],
    [0, 4, 8],
    [2, 4, 6],
  ];
  for (let i = 0; i < won.length; i++) {
    const [x, y, z] = won[i];
    if (squares[x] && squares[x] === squares[y] && squares[y] === squares[z]) {
      return squares[x];
    }
  }
  return null;
};

完成函数也运行良好，但由于 useState 是异步工作的，而且我知道这一点，所以我苦苦挣扎将它放在哪里。如果我把它放在点击函数内部，它就无法对新状态做出反应，只能对之前的状态做出反应。如果我只用 If 语句把它放在外面，它会说渲染次数太多，因为我正在设置赢家等等。我的意思是我还想停止游戏，停止点击事件等等。找不到实现这个的方法。
