[lua] question on tables

if i have a table like this
t = {"h","i"}
how do i turn that into
"hi"
?

Two methods.

Harder way, but with more flexibility:

local str = ''
for i=1, #t do
  str = str .. t[i]
end
print(str) --> hi

Easier way, less flexibility, but perfect for your purposes.

local str = table.concat(t)
print(str) --> hi

In the future, you can also use an optional separator with table.concat if you want.

local str = table.concat(t, ',')
print(str) --> h,i
