ROOT

Note:This page is named ROOT because wiki pages are not allowed to have angle brackets in their names.
<<<ROOT>>> is an internal Roblox class, that all classes (including the Instance class) inherit from.
Unlike the Instance class, this class has no members at all.

It used to be shown in the API Dump, though this is no longer the case.

It can still be exposed using the IsA method, as seen in the example below:

local part = Instance.new("Part")
print(part:IsA("<<<ROOT>>>"))
true

Overall, there is no real significance to this class, as all classes available to developers simply inherit the Instance class.
