-- closures are anonymous function in a function

local function currentNumber() -- scopes can be used in functions aka local or global
  i = 0 -- create a variable called 'i' and assigned it to a number '0'
  print("lol")
  return function() -- create an anonymous function and return it (also called a closure)
    i = i + 1 -- add 1 to the variable i
    print("lol")
    return i -- return the variable i so the print() function will print the value inside the 'i' variable
  end
end

print("==================================")

-- you can assigned a function to a variable
local first = currentNumber() --if a function was assigned to a variable then the function will execute

print("==================================")

print(first()) -- prints out the return values in the function
print(first) -- PROBLEM HERE: why does it print out the function id or something, it didn't print out the current value of the variable
-- 'i'...

print("==================================")

print(currentNumber()) -- prints out what needs to be printed in function and prints out the function id

print("==================================")

currentNumber() -- execute the function block

print("======================================")
