Ep 11: Search Hacker News with ZIO and magic

If you're new to this series I make videos about Scala (both old and the new version 3), functional programming, category theory and more.

This time lets look at how to build a program with ZIO. I walk you through which libraries I use, how to structure the program and how to test it.

You can get the code for this video here:
