I need to make a DataStore. Can you please copy and paste the full script? [closed]

Please, help! I need to make a DataStore for this:

-- Creates a leaderboard that shows player variables
    local function onPlayerJoin(player)
        local leaderstats = Instance.new("Folder")
        leaderstats.Name = "leaderstats"
        leaderstats.Parent = player

        local gold = Instance.new("IntValue")
        gold.Name = "Gold"
        gold.Value = 0
        gold.Parent = leaderstats

        local items= Instance.new("IntValue")
        items.Name = "Molecules"
        items.Value = 0
        items.Parent = leaderstats

        local spaces = Instance.new("IntValue")
        spaces.Name = "Spaces"
        spaces.Value = 2
        spaces.Parent = leaderstats

    end
