Easy questions about lua

coderontheroad

Hi,

I am new in lua language so i want to ask something about it. I guess what it is but just make sure what it is

First; {} are this brackets represent the like array object ?

Second; while executing functions in some example codes use functionName{} insteadof functionName({}). Is it same thing or not ?

Third; again i saw in the example codes "#self.name" what is it ? why use # this character ?

And lastly any advise about difference like that from other languages ? i know as3,php,js and now learning lua

Hello @coderontheroad

1) Yes {} are called tables in lua, but basically they are arrays.
Making indexed array

local t = {"value1", "value2", "value3"}

or associative array

local t = {key1 = "value1", key2 = "value2", key3 = "value3"}

2) Exactly as you said, it is for passing table directly function{} is the same as function({})

3) symbol # takes the number of elements in indexed array

local t = {"value1", "value2", "value3"} print(t) --prints 3   local t = {key1 = "value1", key2 = "value2", key3 = "value3"} print(t) --prints 0

4) Lua is pretty much the same as JavaScript (at least closest from what you have mentioned)

Having objects and anonymous functions, and json is like tables

I've been switching a lot between these two languages recently

Only OOP in Gideros is much prettier than what JavaScript has
