如何为我的Discord.js机器人发出奇偶命令？

npm install discord.js

const Discord = require('discord.js');
const client = new Discord.Client();

client.on('ready', () => {
  console.log(`Logged in as ${client.user.tag}!`);
});

client.on('message', message => {
  if (message.content.startsWith('!奇偶')) {
    const number = parseInt(message.content.split(' ')[1]);
    if (isNaN(number)) {
      message.reply('请输入一个有效的数字！');
    } else {
      if (number % 2 === 0) {
        message.reply(`${number} 是偶数！`);
      } else {
        message.reply(`${number} 是奇数！`);
      }
    }
  }
});

client.login('YOUR_DISCORD_BOT_TOKEN');
