ROOT

Note:This page is named ROOT because wiki pages are not allowed to have angle brackets in their names.


<<<ROOT>>> is the root static object of Roblox's internal ClassDescriptor system. It is the base class of the Instance class, and it has no API members.
While it doesn't serve any practical purposes to developers, you can identify that every object inherits this class by using the IsA function:

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