Which code option would be better?

Question

Lua

I saw on the Internet two options for implementing OOP
First:

oop = {}
function oop:new()
  local oop = {}
  setmetatable(oop, self)
  self.__index = self; return oop
end
function oop:draw()
  --какой-нибудь код
end
function oop:update(dt)
  --какой-нибудь код
end
return oop

Second:

oop = {}
function oop.new()
  loсal oop = {
    update = function (self, dt)
      --какой-нибудь код
    end,
    draw = function (self)
      --какой-нибудь код
    end
  }
  return oop
end

And one thing is of interest, how it will be more correct and faster

Answer 1

more correctly

before writing code, write a test and see how it will be more convenient to use your code

faster

write a test to measure speed and compare
