CountDown Function, does it work well?

Here is a countdown script I currently have. I was wondering is this a good way of making a countdown or no?

Uses replicaservice and promises

local activeCountdown = nil 
local Countdown = 10
local function StartCountDown(Replica)
	-- Cancel any previous countdown if it exists
	if activeCountdown then
		activeCountdown:cancel()  -- Cancels the previous promise/task
		activeCountdown = nil
	end

	-- Create a new promise for the countdown
	activeCountdown = Promise.new(function(resolve, reject, oncancel)
		Replica:SetValue("Counter", 10)

		for count = Countdown, 0, -1 do
			-- Check if the countdown is canceled
			if oncancel() then
				return -- Exit the loop if canceled
			end

			if Replica.Data.Counter ~= nil then
				Replica:SetValue("Counter", count)

				-- When the countdown reaches 0
				if count == 0 and #Replica.Data.Players > 0 then
			
			



			
				end

				task.wait(1)  -- Wait for 1 second
			else
				break -- Exit the loop if the Counter is nil
			end
		end

		-- Countdown completed
		resolve()
	end)


end
