I have downloaded this big open source project which uses spring and ibatis and have everything which OOP offers.

For learning Scala, I am trying to re-write it using play framework. Case classes do offer reduction in boiler plate code. But write now feeling overwhelmed about how to map all this deep inheritance tree, factories etc. from OOP world to functional way of doing things.

I hope someone write side by side mapping of doing things in Scala 2 vs Scala 3.
