how to reference the bot joining a server in discord.js

To reference the bot joining a server in Discord.js, you can use the guildCreate event. This event is triggered when the bot joins a new server. Here's an example of how to use it:

client.on('guildCreate', (guild) => {
  console.log(`Joined a new server: ${guild.name}`);
});

In the above code, client refers to the Discord.js client instance. The guildCreate event is fired whenever the bot joins a new server, and the callback function is executed with the guild parameter representing the guild that the bot joined. You can perform any desired actions within the callback function, such as logging the name of the newly joined server.

Please note that you need to replace client with your actual Discord.js client instance.
