Discord.js Command Handlers

In this tutorial, we will go through several ways of handling commands, from the basic, to the advanced, to the idk-where-to-put-it.

Due to the lack of the advanced department, I will be skipping the basic parts, and will get to it later, maybe.

Note: Apart from the Basic parts, the codes in the other parts are meant to show general directions and concept. There MIGHT be bugs in the code, although they will be small and easy to fix. If you don't know how to fix them, high chance that you are not ready for that part yet.
