lua globals

--Getfenv used the make normal variables into a global variable

myVariable = "Hello, environments" -- Note: a global variable (non-local)
local env = getfenv()
print(env["myVariable"]) --> Hello, environments

lua make variable global

global variables lua

--[[
Global variables don't need a declaration like "local." Instead, you'd just
write like this:
]]--

variable = --value

--[[ 
Note, you don't always have to even assign a value to a variable. You can
use it for the first time and get a value of "nil" which you can update later.
]]--
