I didnt really understand the wiki..
I just would need a true or false statment, and maybe a example if you want to.. c:
--I use datastore for number value's and it work's fine but is Datastore able to save a string value?
Yes, you can save strings using data stores. You can not save instances and mixed list tables.
Example:
local mixedListTable = { [1] = 3 -- The key is a number [2] = "A string" ["A string"] = 5 -- The key is a string [4] = "Another string" } -- Because it has a key that is a string and another that is a number, you will get the error 'keys must be strings'
