If you've ever wanted to build your own Discord bot, you're in luck! The Discord.js library makes it super easy to create powerful and feature-rich bots. So grab your keyboard, and let's dive into the world of Discord bots.

What is Discord.js?

Discord.js is a powerful Node.js library that helps you interact with the Discord API. It simplifies tasks such as sending messages, managing channels, and handling user interactions. Basically, it provides you with all the tools you need to make your bot do awesome things.

Getting Started

To start using Discord.js, you'll first need to have Node.js installed on your machine. Once you have Node.js set up, you can create a new project and install Discord.js with the following command:

npm install discord.js

And that's it! You now have the power of Discord.js at your fingertips.

Creating Your First Discord Bot

Now, let's create a simple bot that greets users when they join a channel. First, you'll need to create a new file called index.js and add the following code:

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 === "!hello") {
        message.channel.send(`Hello, ${message.author}!`);
    }
});

client.login("your-token-goes-here");

Make sure to replace "your-token-goes-here" with your bot's token from the Discord Developer Portal. Once you've done that, start your bot by running:

node index.js

Now, your bot will reply with a greeting whenever someone sends a message with the content !hello. Congratulations! You've just created your first Discord bot using Discord.js.
