Rúnar Bjarnason Libri

This tutorial is designed for programmers eager to learn functional programming (FP) and apply it in their coding practices. It takes readers through a logical and clear progression from basic techniques to advanced topics, featuring concrete examples and exercises that illuminate the principles of FP. The book emphasizes a software development style that focuses on functions independent of program state, leading to code that is easier to test, reuse, and parallelize, while also being less prone to bugs. Scala, a JVM language with strong FP support, is introduced as an ideal starting point due to its familiar syntax and seamless interoperability with Java. No prior experience with FP is necessary, although some familiarity with Scala or Java is beneficial. Inside, readers will discover key concepts of functional programming, the rationale behind FP, guidance on writing multicore programs, and exercises to reinforce understanding. The authors, Paul Chiusano and Rúnar Bjarnason, are recognized experts in FP with Scala and are core contributors to the Scalaz library, ensuring that readers receive knowledgeable insights throughout their learning journey.
