Differences between local functions

#1

Hi to all! I just wondering, is any differences between next to functions, especially in their visibility outside.

Let’s imagine, that we have some file, which we call from outside outside

local temp = {} return temp

And we create to function inside

function temp:funcOne () -- DO something end temp.funcTwo = function () -- DO something end

Is any difference? Because as I know we can call both of the function by following:

-- some file local var = require ("temp") -- got all table with two functions inside -- First way var:funcOne() var:funcTwo() -- Second way var.funcOne() var.funcTwo()

Only differences I see is a syntax, but what actually happend?

var:funcOne()  

is for implementing method for Object Oriented Programming and is invoking the self property by using colon " : " rather than declairing it like this

 var.funcOne(self)  
#3 
var:funcOne()  

is for implementing method for Object Oriented Programming and is invoking the self property by using colon " : " rather than declairing it like this

 var.funcOne(self)
