如果用户在discord.js中提供了20封邮件(超过14天)进行批量删除，如何仅删除10封邮件

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

client.login('YOUR_DISCORD_TOKEN');

const guild = client.guilds.cache.get('YOUR_GUILD_ID');

const channel = guild.channels.cache.get('YOUR_CHANNEL_ID');

channel.messages.fetch({ limit: 20 })
  .then(messages => {
    // 在这里进行邮件删除操作
  })
  .catch(console.error);

const filteredMessages = messages.filter(message => {
  const messageAge = Date.now() - message.createdTimestamp;
  const daysAgo = messageAge / (1000 * 60 * 60 * 24);
  return daysAgo > 14;
}).array().slice(0, 10);

Promise.all(filteredMessages.map(message => message.delete()))
  .then(() => console.log('邮件删除成功'))
  .catch(console.error);

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

client.login('YOUR_DISCORD_TOKEN');

client.on('ready', () => {
  const guild = client.guilds.cache.get('YOUR_GUILD_ID');
  const channel = guild.channels.cache.get('YOUR_CHANNEL_ID');

  channel.messages.fetch({ limit: 20 })
    .then(messages => {
      const filteredMessages = messages.filter(message => {
        const messageAge = Date.now() - message.createdTimestamp;
        const daysAgo = messageAge / (1000 * 60 * 60 * 24);
        return daysAgo > 14;
      }).array().slice(0, 10);

      Promise.all(filteredMessages.map(message => message.delete()))
        .then(() => console.log('邮件删除成功'))
        .catch(console.error);
    })
    .catch(console.error);
});
