How to make a Discord bot operate across multiple guilds?

I’m in the process of developing a Discord bot while learning JavaScript, and I have some queries regarding its functionality:

Given that JavaScript doesn’t support multithreading, how can the bot manage multiple events from different servers? Specifically, how does it handle variables? For example, if the same event occurs in multiple servers, will the values interfere with each other?

Here’s an example of my code for context:

const { Client } = require('discord.js');

const bot = new Client();
const apiKey = 'your-token';

bot.on('ready', () => {
  console.log('Bot is operational!');
});

bot.on('message', msg => {
  if (msg.content.startsWith('nyan!')) {
    let command = msg.content.slice(5);  // Store command in a variable

    if (command.includes('(')) {
      switch (command.split('(')[0].trim()) {
        case 'createChannel':
          console.log(bot.guilds);
          bot.guilds.cache.forEach(guild => {
            console.log(guild);
            guild.channels.create('new-general', { type: 'text' });
          });
          break;
      }
    } else {
      switch (command) {
        case 'ping':
          msg.channel.send(`Ping: ${bot.ws.ping}`);
          break;
        case 'shutdown':
          msg.channel.send("I'll return").then(() => {
            bot.destroy();
            process.exit();
          });
          break;
      }
    }
  }
});

bot.login(apiKey);

When dealing with a Discord bot handling events across various servers or guilds, while JavaScript lacks multithreading natively, its asynchronous nature significantly aids in maintaining operation fluidity. Each event is processed in the order it is received by using the event loop — allowing for simultaneous processes without interference with each other. It’s generally all about how you structure your bot’s logic; consider storing variables and state information specific to each guild or user in a database like SQLite or MongoDB to avoid cross-talk between server data. Utilizing environmental variables for token management can also enhance security across multiple servers.

Using discord.js handles ur events across different servers smoothly due to its event-driven model. For variables, you can define them within the event handler so they don’t clash. Consider per-server memory like map or custom objects for storing data unique to each guild if database setup feels complex at first.
