How to insert variable into a string

[guisalum]

I know this is a dumb question. For example I have the variable

local var = "world"

and I want to create another variable but I want t oinsert this 'var'.

For example

local anotherVar = "Hello " var "."

If you know Php it'd be like this

$var = "world";
$anotherVar = "Hello " . $var . ".";

How do I do this?

thanks

I ot it (just use double dots) hehe

Can I use variable to return value of tables?

for instance:

I have the table

local table = {"hello", welcome = {item1 = "hello", item2 = "world"}}

But I wnat to call the table not using table.welcome.item1

I want to use like

local table = {"hello", welcome = {item1 = "hello", item2 = "world"}}
local var = "welcome"

table.var.item1

Is it possible?
table.welcome.
