-- While the code below IS lua, I think it's a bit hard to understand..-
-- Another way to do it, without confusing yourself, is just doing it like this:

local firstTable = {}

firstTable.Apples = "Apple"
firstTable.Bananas = "Banana" -- I'm adding new variables inside the table by using a dot,
-- Seperating themselves from the table, and the variable!
-- (A variable is something that can be used as a faster way to use values..
-- For instance, printing a string.)

print(firstTable.Apples, firstTable.Bananas)




-- IF YOU WANT TO DO IT FASTER vv


local secondTable = {}

secondTable.Apples = "Apples"
secondTable.Bananas = "Bananas"

local Apples, Bananas = secondTable.Apples, secondTable.Bananas
print(Apples, Bananas)

-- Lua Basics
-- I made this because I'm bored.
-- 1. Variables
-- (1.1) Local Variables
local newVariable = "Something"
local newVariable2 = 1
local newVariable3 = true

-- (1.2) Global Variables
newVariable4 = "Insert text here"

-- 2. Tables
local newTable = {"Apple", "Pencil", "Eraser"}

-- 3. If Statement
if 1 + 1 == 2 then
  print("Cool, you didn't fail math.")
end

-- 4. for loops
for i = 1, 3 do
  print("Successfully looped " .. i .. " times.")
end

-- 5. While loops, break
local i = 1
while true do
  i = i + 1

  if i == 10 then
    break -- Basically exits the loop
  end
end

-- 6. Functions
local function newFunction()
	print("yes")
end
 
newFunction()

-- "n" and "n2" are parameters
local function addNumbers(n, n2)
  print(n + n2)
end

addNumbers(3, 4) -- prints 7

-- 7. varargs
function Plus(...)
    local result = 0
    for _, value in ipairs({...}) do
        result = result + value
    end
    return result
end
print(Plus(7, 5, 2, 5)) -- prints 19
print(Plus(1, 2, 3, 4, 5, 6, 7, 8, 9)) -- prints 45

how ... arguments work

so i assume this is how you make a function-

functionfoo(x,y,z)...end

let me intruduce you to ...

functionfoo(...) ... end

the ... in a functions params pretty much means agruments but without
knowing what its like a unpacked table the are values but no key to access them.

foo(...) -> foo(x,y,z)
foo(...) local x,y,z = ... end -> foo(x,y,z) end

so why use these?

when you are making a functions who are getting accessed from diffrent scripts
and you dont want to make if statements to filter out the passed arguments
this is what i mean:

local module = {}

local private = {}

function private.add(self, x,y)
	return x+y;
end

function private.addum(self, x,y,z)
	return x+y+z;
end

function module:access(key, ...)
	return private[key](nil, ...) -- the nil is self
end

result = module:access("add", 1, 2)
print(result) -- should print 3
result = module:access("addum", 1,2,3, 4)
print(result) -- should print 6

its more to do with when trying to make a gateway to multiple functions
its usefull you can just use the needed arguments and if more arguments are
passed who wont be used it will just ignore and move on.
