What can i use arguments optional in function

[Rewlaxe (Lazxr)]

function constructor.GetSelf(self: constructor)
	local lowerText = self.Objectif:lower():: string
	local splitText = lowerText:split(" ")
	
	if splitText[1] == "kill" then
		print(`you objectif is a kill {splitText[2]}`)
	elseif splitText[1] == "found" then
		print(`you objectif is a found {splitText[2]}`)
	end
end
``` I did like it I don’t know if it’s okay
