What does the "Points" do in the datastore?
Is it just a string that your saving it under? Or is it a service kinda like PointsService?
local DataStore = game:GetService("DataStoreService"):GetDataStore("Points")
It's basically accessing a data set from your game (universe, or just place?) stored in Roblox servers.
So, yes, it is a string that you're saving it under.
"With Data Stores you can store arbitrary data which persists even when games are not running and can be accessed by all instances of a place in your game universe" (Data store).
