In this coding tutorial, we cover the basics of Discord.js for creating Discord bots with JavaScript. We start with a simple Bot that responds to text triggers, then we implement the bot's ability to listen for Reactions. You need node.js v12.0.0 or newer to use Discord.js! Check your version by running `node -v` in a terminal.

Do you have a neat idea for a Discord Bot? Let me know in the comments!
