javascript reference error is not defined
//If you get a javascript reference error, It means that your using a word that
//needs to be defined. For example, If I wrote "cookie += 1;", I would get this
//error because cookie isn't defined. If you want to define something, you need
//to create a variable that defines "cookie". You could do this:
let cookie = 0;
//Basically, your giving "cookie" a value, so that whenever you write "cookie"
//it refers to "0". Here is another example:
const Discord = require("discord.js");
//This means that "Discord" will now reffer to the discord.js extension.
