How can I improve this data store method?

I'm always looking to learn and stuff like that, can any of you tell me how I could better this DataStore? and tell explain why? thanks

local player = game:GetService("Players")
local RS = game:GetService("ReplicatedStorage")
local DS = game:GetService("DataStoreService")

local data = {
    ["Data1"] =  DS:GetDataStore("Data1"),

}

player.PlayerAdded:connect(function(plr)

    local success, err = pcall(function()
    local userID = plr.userId
        local Stats = Instance.new("Folder")
    Stats.Name = "Stats"
        local Data1 = Instance.new("IntValue")
    Data1.Name = "Data1"
    Data1.Value = data["Data1"]:GetAsync(userID)or 1

    Stats.Parent = plr
    Data1.Parent = Stats
end)
if success then print("Stats in game!")

end
    end)

player.PlayerRemoving:connect(function(plr)
    local userId = plr.userId
    local Stats = plr:WaitForChild("Stats")

        data["Data1"]:SetAsync(userId, Stats.Data1.Value)


end)
