How do I use Data store to share data between two places?

If I used data store to save a value in one place, how would I get that saved value in the other place?

Data Store script in the first place:

local quirkstore = game:GetService("DataStoreService"):GetDataStore("Quirk")

game.Players.PlayerAdded:connect(function(plr)

    local stats = Instance.new("IntValue", plr)
    stats.Name = "leaderstats"

    local quirk = Instance.new("StringValue", stats)
    quirk.Name = "Quirk"
    quirk.Value = quirkstore:GetAsync(plr.userId) or ""
    quirkstore:SetAsync(plr.userId, quirk.Value)        

end)

game.Players.PlayerRemoving:connect(function(plr)
    print("Saving Player Data")
    quirkstore:SetAsync(plr.userId, plr.leaderstats.Quirk.Value)
    print(plr.leaderstats.Quirk.Value.." Has been saved")


end)
