OOP concept

local _M = {} -- module table

_M.someProperty = 1 -- class properties

local function createText()
   -- local function are still valid, but not seen from outside - "private"
end

local privateVar -- so do local variables

_GLOBAL_VAR -- without local it's global

function _M.staticMethod(vars)
    -- this is class method like function (dot)
    -- there is no "self"
end

function _M:someMethod(vars)
    -- this is object method like function (colon)
    -- there is "self"
end

return _M -- return this table as a module to require()

return _M
