How do I print the number of {} table?
1 | local instances = {} |
2 |
3 | for _,child in pairs(workspace.Servers:GetChildren()) do |
4 | if child:IsA("Folder") then |
5 | table.insert(instances, child) |
6 | end |
7 | end |
8 |
9 | print(unpack(instances)); |
In the output, it would say, "Folder Folder" But I Want it to become "1 2" counting the specific objects instead of nouning them. I've been trying to go in the wiki but I can't really find anything... Thanks in advance!

Use the unary length operator, #.
This is all you need. The unary length operator gets how many elements are in a table.
So don't unpack it, you can instead just get the length:
1 | print(#instances) |
However this won't print 1 2, it will just print 2. If you really want to print the former, you can insert the index instead of the child reference:
1 | for pos, child in ipairs(workspace.Servers:GetChildren()) do |
2 | if child:IsA("Folder") then |
3 | table.insert(instances, pos) |
4 | end |
5 | end |
And you can unpack it
1 | print(table.unpack(instances)) |
