在javascript上构建一个石头、布和剪刀游戏

// 定义游戏选项
const options = ["石头", "布", "剪刀"];

// 生成电脑的随机选择
function computerPlay() {
  const randomIndex = Math.floor(Math.random() * options.length);
  return options[randomIndex];
}

// 判断胜负
function playRound(playerSelection, computerSelection) {
  if (playerSelection === computerSelection) {
    return "平局！";
  } else if (
    (playerSelection === "石头" && computerSelection === "剪刀") ||
    (playerSelection === "布" && computerSelection === "石头") ||
    (playerSelection === "剪刀" && computerSelection === "布")
  ) {
    return "你赢了！";
  } else {
    return "你输了！";
  }
}

// 运行游戏
function game() {
  let playerScore = 0;
  let computerScore = 0;

  for (let i = 0; i < 5; i++) {
    const playerSelection = prompt("请选择：石头、布或剪刀").toLowerCase();
    const computerSelection = computerPlay();

    console.log(`你选择了：${playerSelection}`);
    console.log(`电脑选择了：${computerSelection}`);

    const result = playRound(playerSelection, computerSelection);
    console.log(result);

    if (result === "你赢了！") {
      playerScore++;
    } else if (result === "你输了！") {
      computerScore++;
    }
  }

  console.log(`最终得分：你 ${playerScore} - ${computerScore} 电脑`);
  if (playerScore > computerScore) {
    console.log("恭喜你，你赢得了游戏！");
  } else if (playerScore < computerScore) {
    console.log("很遗憾，你输掉了游戏！");
  } else {
    console.log("游戏结束，平局！");
  }
}

// 运行游戏
game();
