Functional Programming in Scala

Posted on 13 June 2018 by Rúnar Bjarnason

Functional programming FP is a programming style emphasizing functions that return consistent and predictable results regardless of a program s state As a result, functional code is easier to test and reuse, simpler to parallelize, and less prone to bugs Scala is an emerging JVM language that offers strong support for FP Its familiar syntax and transparent interoperability with existing Java libraries make Scala a great place to start learning FP Functional Programming in Scala is a serious tutorial for programmers looking to learn FP and apply it to the everyday business of coding The book guides readers from basic techniques to advanced topics in a logical, concise, and clear progression In it, they ll find concrete examples and exercises that open up the world of functional programming.Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning Also available is all code from the book.

wanting to really learn and understand Scala It s not that the book will necessarily give you mastery of the language only time and experience gained through writing lots of code can do that, though they help by giving the reader lots of good exercises But it will alter your view of the language and very likely teach you a new way of approaching problems The...Bitirir bitirmez yazd m bir ka c

in Scala by Chiusano and Bjarnason can be considered the most advanced Scala programming book published so far in a sense, it can be compared to SICP Half of one of my bookshelves is occupied by Scala books, including Scala in Depth, but none of them takes the concept of functional programming as serious as this book, and pushes it to its limits that much This, in turn, means that most of the Java

as this book, and pushes it to its limits that much This, in turn, means that most of the Java programmers including very senior ones , as well as Scala programmers with some experience should prepare themselves to feel very much like a newbie again.But why the need for such a book, and what s all that noise about functional programming Here is my favorite description of functional programming given by Tony Morris Supposing a program composed of parts A, B, C, D, and a requirement for program of parts A, B, C...This book has an outstanding goal teaching FP principles to those who might have close to no experience with functional programming I reckon that s not doable during the coarse of a few hundred pages Fortunately, this book delivers that what it has promised.All the book s materials are split into the chunks of textual information and exercises you re encouraged to do in order to fully absorb all the meaningful information you might otherwise forget in a day.Since

will bring you up to speed with modern functional programming Knowing Scala is useful but not required All important concepts like monads, applicative functors and traverses are introduced in natural

the book demands too much from its readers.
