how to check what an item in a table is

[split elk]

so basically im tryna make a function that will merge any 2 tables into 1, and i wanted to allow the second table to contain tables that can be broken down into their individual objects, but the problem is that i'm having issues detecting if an item in the table is a table, i tried the :IsA() function, but that produces an error since I'm testing with a table of strings and not a table of tables. Any tips?

heres the code

local module = {}

function mergeTables(table1:SharedTable,table2:SharedTable,BreakTable2:boolean) -- BreakTable2 determines if table2 is broken into objects
    for i = 1, #table1 do
        if table2[i]:IsA("SharedTable") and BreakTable2 == true then
            mergeTables(table1,table2[i])
        else
            table.insert(table1,table2[i])
        end
    end
    
    return table1
end

function module.merge(baseTable:SharedTable, addTable:SharedTable, BreakTable:boolean)
    local result = baseTable
    
    result = mergeTables(result,addTable,BreakTable)
    
    return result
end

return module

the proper way to check if something is a table is to use type()

Also use pairs() instead of numeric indexing so it works with any table structure not just arrays

[spark moat]

pairs is not needed anymore in LUAU, you can just iterate normally

[split elk]

it worked

holup

when testing with tables in tables it just adds the table to the base table

[cosmic oyster]

don't use type(), instead use typeof() because it's faster and built-in for roblox

Instead of for looping you can just do table.unpack

holup i found the problem

actually give me a sec

yeah i did

its not detecting that the item is a table

this is the if statement line ```lua
if typeof(table2[i]) == SharedTable and BreakTable2 == true then

fixed it

nvm

everything works now

just changed the sharedtable to a string, "table"

[split elk]

update: it decided to stop working

👀

any errors this time

[split elk]

"attempt to index nil with number" but the table its indexing does exist
