A quick and dirty fleshing out of the discord.js event listeners .
Discord.Js version 11 has fallen behind the current API specs therefore is no longer a valid library version to use. However somepeople still use it?! Anyways Discord.js v11 will hard crash if you encounter a stage channel, so just switch to v12.
The original code for the discord.js-v11-cheatsheet.js wasn't from me.

The original code was made for discord.js v11. This code can be found in discord.js-v11-cheatsheet.js.
However v12 was released and some things have changed. These changes can be found in discord.js-v12-cheatsheet.js.
