Is this data module I made good and would work well for bigger use?

[x6nnx]

I made a small data store module and I wanted to know if this would be a good way of saving a players data efficiently

--[[

DOCUMENTATION:

LightData.SetDataStore(Name, Scope) | Line 166
	Sets the datastore name and scope for LightData.
	Name: string
	Scope: string

LightData.SetDataTemplate(Template) | Line 170
	Sets the data template for LightData.
	Template: table
	
LightData:GetData(player) | Line 176
	Gets the player's data.
	player: Player
	returns: table
	
LightData:SaveData(player, remove) | Line 186
	Saves the player's data.
	player: Player
	remove: boolean

Looks pretty good. From a quick glance, there’s a couple of things I wanted to ask/check:

1. Why are you using a colon for some of the module functions?
   If you aren’t needing the item itself, there’s no point in doing it.
   You’re just doing Cache.Cache, etc. where you just index the cache object.
   I’d recommend either changing it to self or just using a dot.
2. Use UpdateAsync. It allows for comparison code, and has other safety features that SetAsync does not. SetAsync should be used with caution and only when you are making a safer save, e.g. a leaderboard, which should just mimic data.
