Hello, developers! I want to get the total amount of items in a table. This is what I mean:

local responses = {
	"Hello!",
	"This a test!",
	{
		":D",
		">:("
	}
}

--I'm ALSO trying to get the other table inside the "responses" table which contains ":D" and ">:("

print(table.getn(responses)) --> 3
print(#responses) --> 3
How do I get the amount of instances in a table?

Hey, for this you would need to reiterate for values that are a table:

local my_table = {
	"Hello",
	"Test1",
	{
		"Hello again",
		"Test 2"
	}
}

local function getNumberOfItems(tbl)
	local items = 0
	for index, value in pairs(tbl)do
		if typeof(value) == "table" then -- if the value is a table we reiterate to get the number of items in it
			items += getNumberOfItems(value) -- you can add 1 if you want to count the table aswell
		else
			items += 1
		end
	end
	return items
end

local items = getNumberOfItems(my_table)
print(items) -- 4
