This series aims to reorient your perspective toward a functional mindset, helping you look at common problems in new ways and find ways to improve your day-to-day coding. It explores functional programming concepts, frameworks that allow functional programming within the Java language, functional programming languages that run on the JVM, and some future-leaning directions of language design.

Use Scala and Clojure to solve in-depth problems with two sets of patterns: object-oriented patterns that become more concise with functional programming, and natively functional patterns. Your code will be more declarative, with fewer bugs and lower maintenance costs. Functional languages have their own patterns that enable you to solve problems with less code than object-oriented programming alone.

Functional Programming Patterns in Scala and Clojure: Write Lean Programs for the JVM

Scala is used to construct elegant class hierarchies for maximum code reuse and extensibility and to implement their behavior using higher-order functions. Knowing how and where to apply the many Scala techniques is challenging. Looking at Scala best practices in the context of what you already know helps you grasp these concepts quickly, and helps you see where and why to use them. This book begins with the rationale behind patterns to help you understand where and why each pattern is applied. You will discover what tail recursion brings to your table and will get an understanding of how to create solutions without mutations. We then explain the concept of memorization and infinite sequences for on-demand computation.

Functional Programming Patterns in Scala and Clojure Book

In computer science , functional programming is a programming paradigm where programs are constructed by applying and composing functions. It is a declarative programming paradigm in which function definitions are trees of expressions that map values to other values, rather than a sequence of imperative statements which update the running state of the program. In functional programming, functions are treated as first-class citizens , meaning that they can be bound to names including local identifiers , passed as arguments , and returned from other functions, just as any other data type can. This allows programs to be written in a declarative and composable style, where small functions are combined in a modular manner. Functional programming is sometimes treated as synonymous with purely functional programming , a subset of functional programming which treats all functions as deterministic mathematical functions , or pure functions. When a pure function is called with some given arguments, it will always return the same result, and cannot be affected by any mutable state or other side effects. This is in contrast with impure procedures , common in imperative programming , which can have side effects such as modifying the program's state or taking input from a user.

Apr 14, Sebastian Gebski rated it it was ok. No, just no. I was also wondering what's the point in writing a book that covers FP for both Scala and Clojure - these 2 differ a lot and I don't think there are many people truly capable in both. I feel disappointed. PragProg usually promises and delivers, but this time it just didn't work. Nov 15, Rod Hilton rated it really liked it.

Functional programming

It is an extremely well-built safety rope for those crossing the bridge between two very different worlds. Consider this mandatory reading. The functional patterns are sectioned in the back of the book separate from the functional replacements of the object-oriented patterns, making the book handy reference material. As a Scala programmer, I even picked up some new tricks along the read. Michael Bevilacqua-Linn has been programming computers ever since he dragged an Apple IIGS into his fifth grade class to explain loops and variables to pre-teenagers.

This book introduces you, the experienced Java programmer, to Scala and Clojure: practical, production-quality languages that run on the JVM and interoperate with existing Java. Do not let people you can not do it. You can actually do a lot more harm without using any Clojurd. And think everything should start with a bang. Clojure are financially independent but a scholarship is always appreciated.

    This book sticks to the meat and potatoes of what functional programming can do for the object-oriented JVM programmer. The functional patterns are sectioned.
