How to make a discord.js bot say custom messages in a specific channel & tag a user in a message

问题

So, I wanted to create my own discord server for my friends and me, and I wanted it to have some bot features... So I got into coding.. long story short I messed it up and after hours of trying to find the solution I gave up.

The first one is a word filter, works perfectly fine, I just cannot tag anyone.. It's supposed to delete the message that's said and give out a message, just like "@example, don't say that!"

client.on('message', async(msg) => {
    
    if(msg.author.bot) return;
    if(!msg.guild) return;

    var array = ['example1, 'example2'];

    if(!msg.member.hasPermission('MANAGE_MESSAGES')){
        if(array.some(w => ` ${msg.content.toLowerCase()} `.includes(` ${w}`))){
            msg.delete();
            msg.channel.send(`${client.user.tag}`)
            return;
        }
    }
        
});

My second problem: I tried creating a command that every time you type in (prefix)say + "text" on Discord, the bot will say that message. the best would be if it's possible that you type in all the commands in ONE text-channel and have the ability to choose to what channel I want the bot to type that message too. the simple variant would be fine aswell for me. here is my code:

const isValidCommand = (message, cmdName) => message.content.toLowerCase().startsWith(prefix + cmdName);

require('dotenv').config();

client.on('message', function(message) {
    if(message.author.bot) return;

    else if(isValidCommand(message, "say")) {
        let marketing = message.content.substring(5);
        let marketingchannel = client.channels.cache.get('766732225185054740');
        let logsChannel = client.channels.cache.find(channel => channel.name.toLowerCase() === 'logs');
        if(logsChannel)
            logsChannel.send(marketing);
    }
});

I really hope that I will get it to work..

Thanks in advance!

First problem

User.tag doesn't actually mention the user. A user's tag in a combination of their username and discriminator.

'Lioness100'; // my username
'4566'; // my discriminator

'Lioness100#4566'; // my tag

There are a few ways to mention someone in a message. The first one is the built-in Message.reply() function which will send the given message, prepended with <mention of author>,

The second method would be converting the User/GuildMember object to a string. Discord will automatically parse it as a mention.

The third and most versatile method would be using mention syntax. For users, it's <@id>.

All mention syntax

Your second problem

I'm not quite sure if something is wrong with your code, or what exactly your asking, but I think you want channels to be dynamically chosen per message. You can do this by creating an args variable.

// new usage:
// {prefix}say channelName message

client.on('message', function(message) {
 if (message.author.bot) return;

 // split string by every space => returns an array
 const args = message.content.slice(prefix.length).split(/ +/);

 // removes the first element (the command name) and stores it in this variable => returns a string
 const command = args.shift().toLowerCase();

 // now it's much easier to check the command
 if (command === 'say') {
  // the first element of `args` is the first word after the command, which can be the channel name
  // we can then find a channel by that name => returns a Channel or undefined
  const channel = message.guild.channels.cache.find(
   (c) => c.name === args[0]
  );

  if (!channel)
   return message.channel.send(`There is no channel with the name ${args[0]}`);

  // join all args besides the first by a space and send it => returns a string
  channel.send(args.slice(1).join(' '));
 }
});
