E-Books →Applied Functional Programming in Scala

This book explores core functional principles like immutability, pure functions, and referential transparency. You will gain a deep understanding of the mathematical underpinnings through category theory concepts like Functors and Monads, and then apply these practically using Scala functional features and leading libraries such as Cats and ZIO. The book also covers handling effects and I/O, advanced functional patterns, and using specialized tools to build functional web, database, and streaming solutions. With real examples and patterns, it shows how these ideas can simplify code, improve testability, and increase system resilience.
By the end of this book, you will have a theoretical understanding and practical proficiency in building high-quality, maintainable applications using functional programming in Scala.
What you will learn
● Implement Scala higher-order functions, currying, and Option/Either.
● Understand Functors, Monads, and their category theory relevance.
● Utilize Cats type classes for extensible functional programming.
● Build scalable applications using FP patterns.
● Manage side-effects and I/O functionally using effect systems.
● Real-world use of functional programming.
Who this book is for
This book is for software engineers, developers, and architects seeking to write more composable, testable, and expressive code. Readers should have a basic understanding of programming concepts, but no prior functional language experience is required.
