How will i convert this to store data?? (Long Code)

I am not good at listening, so pls give me a small example from my code or whatever you can :)

---[CODE BY ALEXANDRE (aleandroblingo)]

local Module = {}

function Module:Inject()

end

function onPlayerEntered(newPlayer)
    wait(.5)

return Module

I know its something like this

local ds = game:GetService("DataStoreService"):GetDataStore("stats")

stats={"Reputation","Cash","Exp","MaskColor","MaskPattern","Primary","Secondary","Armor","Equipment"}--change these to whatever stats you want
game.Players.PlayerAdded:connect(function(plyr)
    local a=Instance.new("NumberValue")
    a.Parent=plyr
    a.Name="leaderstats"
    for i=1,#stats do
        local stat=Instance.new("NumberValue")
        stat.Parent=a
        stat.Value=0
        stat.Name=stats[i]
    end
    local child=plyr.leaderstats:GetChildren()
    for i=1, #child do
        child[i].Value=ds:GetAsync(plyr.userId..child[i].Name)
    end
end)

game.Players.PlayerRemoving:connect(function(plyr)
    local child=plyr.leaderstats:GetChildren()
    for i=1, #child do
        child[i].Value=ds:SetAsync(plyr.userId..child[i].Name,child[i].Value)
    end
end)
