How can my DataStore2 script be improved?

Help and Feedback Code Review
#1

Hello! How is it going?
I recently scripted a DataStore2 saving method which works and everything. I just want to know if my code can get any better!

local DataStore2 = require(game:GetService("ServerScriptService").DataStore2)
local CombinedDataStore = DataStore2.Combine("TimeTrials", "TimeTrialsBackup")

local DefaultTable = {
	["Under_The_Sea"] = 0,
	["Small_World"] = 0,
	["Jurassic"] = 0,
	["Piggy_Speedway"] = 0,
	["Sandy_Secrets"] = 0,
	["Space_Heights"] = 0,
	["Space_Highway"] = 0,
	["Eggsburg"] = 0,
	["Tilted_Road"] = 0,
	["Space_Turnpike"] = 0,
}

game:GetService("Players").PlayerAdded:Connect(function(Player)
	local DataStore = DataStore2("TimeTrials", Player)
	
	local Data
	
	local Success, Error = pcall(function()
		Data = DataStore:GetTable(DefaultTable)
	end)
	
	if not Success then
		error(Error)
	end
	
	local TimeTrialsData = Instance.new("BinaryStringValue")
	TimeTrialsData.Name = "TimeTrialsData"
	TimeTrialsData.Parent = Player
	
	for Map, Value in pairs(Data) do
		TimeTrialsData:SetAttribute(Map, Value)
	end
	
	for Map, Value in pairs(DefaultTable) do
		if not TimeTrialsData:GetAttribute(Map) then
			TimeTrialsData:SetAttribute(Map, Value)
		end
	end
end)

game:GetService("Players").PlayerRemoving:Connect(function(Player)
	local DataStore = DataStore2("TimeTrials", Player)
	local DataToSave = {}
	
	for Map, Value in pairs(Player.TimeTrialsData:GetAttributes()) do
		DataToSave[Map] = Value
	end
	
	local Success, Error = pcall(function()
		DataStore:Set(DataToSave)
	end)
end)

If you have a concern about my code, please let me know. Thanks! WE

Localize the Players service, also you should check if there are any existing players in case that script runs after a player(s) joins.

#3

What do you mean by Localizing the Players service?

And why would be the point of doing this?

#4 
local PlayersService = game:GetService("Players")

This video explains why:

Um don’t I use :GetService()? I thought I did.

#6

You are repeatedly using the Players service, that is the whole point of variables.

Oh sorry for the misunderstanding. I get it now. Thanks!
