我试图为我的discord.js机器人创建一个排行板命令，但是除了第一位的值之外，所有的值都保持为0

const leaderboard = {
  user1: 100, // 示例分数
  user2: 50,
  user3: 75,
};

function handleLeaderboardCommand(message, args) {
  const command = args[0]; // 命令参数，比如"show"或者"update"
  
  if (command === "show") {
    // 显示排行榜
    const leaderboardEntries = Object.entries(leaderboard);
    leaderboardEntries.sort((a, b) => b[1] - a[1]); // 根据分数降序排序
    
    let leaderboardMessage = "排行榜：\n";
    leaderboardEntries.forEach((entry, index) => {
      leaderboardMessage += `${index + 1}. ${entry[0]} - ${entry[1]}\n`;
    });
    
    message.channel.send(leaderboardMessage);
  } else if (command === "update") {
    // 更新分数
    const user = args[1]; // 用户名
    const score = parseInt(args[2]); // 分数
    
    if (isNaN(score)) {
      message.channel.send("无效的分数！");
      return;
    }
    
    leaderboard[user] = score;
    message.channel.send(`已更新 ${user} 的分数为 ${score}！`);
  } else {
    message.channel.send("无效的排行榜命令！");
  }
}

client.on("message", (message) => {
  if (message.content.startsWith("!leaderboard")) {
    const args = message.content.split(" ");
    handleLeaderboardCommand(message, args.slice(1));
  }
});
