There’s never a case where _G should be used anymore. I’d recommend staying as far away from it as possible.
Programmers might avoid working with you and might even not take you seriously for using _G
You can use a ModuleScript, Attributes or CollectionService instead that’s what they are for
A few good reason to avoid _G:
- No intellisense
- Key and Value might not exist upon indexing
- Hard to debug magical table
- Less performant than other alternatives
