You can write your topic however you want, but you need to answer these questions:
What do you want to achieve? Keep it simple and clear!
I’d like to know the difference between datastore and datastore2, the advantages of datastore2, and how datastore2 looks!
What is the issue? Include screenshots / videos if possible!
Nothing, I just want to learn.
What solutions have you tried so far? Did you look for solutions on the Developer Hub?
I tried searching this topic up, but stuff that came up was mostly not informative in any way.
They are not really different. At the end, DataStore2 uses regular Data Stores. It does not use an external service or anything like that. That would be a terrible idea as it would require publicly sharing an API key. But DataStore2 is a module written by Kampfkarren. All documentation is included here: How to use DataStore2 - Data Store caching and data loss prevention
