how to check if a instance has a certain property?

So I was doing a i,v loop on workspace

heres what the code looks like

for i,v in pairs(workspace:GetChildren()) do
	if v.Disabled then
		v.Disabled = true
	end
end

But it saids v.Disabled is not a valid member

and there is no findfirstchild for a property too

Varies, In this case I used a pcall.

If it is errored, it is contained by the pcall and will not break the script. Otherwise v.Disabled will equal true

pcall(function()
	v.Disabled=true;
end);
