Learn Functional Programming (Without Fear)
Briefly

By my standards this is a little book, but it's a little book with an audacious goal: To help OOP developers who use languages like Java, Kotlin, Python, Swift, and C++ learn the concepts that take you to the cusp of using Scala's two main functional programming libraries: Cats Effect and ZIO.
To be clear, when I say 'the cusp' of using those FP libraries, when you finish the book, I want you to be able to look at the initial examples in the Cats Effect and ZIO documentation and think, 'I know what they're doing, and I know why they're doing it.'
I may add more pages in an Appendix, but the meat of the book is planned to be under 200 pages.
Please note that I currently have no intention to create Kindle or ePub versions of this book, so at the very least, the PDF will be the only electronic version you'll be able to buy any time soon.
