Now that our files are set up, we can now write our first Discord.js slash command.

By create custom commands, we extend the functionality of our Discord bot and can make it much more fun and interesting.

We'll start by creating a new file in the commands folder, importing the slash command builder, and defining the data and execute sections of the command. We'll then register the command and test it in the Discord application.

By the end of this lesson, you'll have a solid understanding of how to create custom slash commands in Discord.js. So get ready to dive in and start building!
