Is there a function which searches through all descendants?

I know there's a FindFirstChild function, but I would like to know if there is a function which returns all the descendants, which I specific? [Edit] More specifically, a function which can search through a whole "family tree" and keep searching the children, and its children, etc. and returns all the children which have a specified name? If there isn't, does anyone know how to make one? Thanks!

#What you could do Use a loop to go through all the children, if there are more children, use the function to count to see if there are more children!

#Final Product We can use :GetChildren() to get the children of the original object, then use it again to do the function again to the descendants. Edit the following codes to your liking! ###Count Descendants:

local descendants = 0

function count(obj) --counts descendants only
	if #obj:GetChildren() > 0 then
		for _,v in pairs(obj:GetChildren()) do
			descendants = descendants+1
			count(v)
		end
	end
end

count(workspace.Model) --counts up the descendants

print(descendants) --Print the number of items inside of a model for example.

###Change Descendants Color's

function count(obj)
	if #obj:GetChildren() > 0 then
		for _,v in pairs(obj:GetChildren()) do
			v.BrickColor = BrickColor.Random()
			count(v)
		end
	end
end

color(workspace.Model) --colors all the descendants

Hope it helps!

I think what youre looking for can be found by using loops and tables.

for i, child1 in pairs(workspace.Object:GetChildren()) do -- loops through each child of the object
print(Child1)

--OPTIONAL getting that childs child

for i, child2 in pairs(Child1:GetChildren()) do -- loops through the childs children
print(child2)
end
