How do I check if parts in table were touched?

from what I understand, while loops can be very demanding to a player's gameplay, slowing the game down. So while I was making this I could find no other way of doing this without a while loop. Is there a better way to check if a part in a table has been touched?

My attempt:

local model = game:GetService("Workspace").Model
local table = {}
for i,v in pairs (model:GetChildren()) do -- This part is different, It's for the sake of the site
	table.insert(table,#table+1,v)
end
for i,v in pairs(table) do
	v.Touched:Connect(function()
		print("Touched")
	end)
end

You can actually use a single table [as called by :GetChildren()] to run this function

local model = workspace:WaitForChild("Model")

local function Fired()
	print("Touched")
end

for _, parts in pairs(model:GetChildren()) do
	parts.Touched:Connect(Fired)
end

If you use a local event, then by using the for loop to check the array, anytime an iterated part is touched, this pre-defined function will fire.
