Overview of this book

This book teaches you how to build and contribute to Scala programs, recognizing common patterns and techniques used with the language. You’ll learn how to write concise, functional code with Scala. After an introduction to core concepts, syntax, and writing example applications with scalac, you’ll learn about the Scala Collections API and how the language handles type safety via static types out-of-the-box. You’ll then learn about advanced functional programming patterns, and how you can write your own Domain Specific Languages (DSLs). By the end of the book, you’ll be equipped with the skills you need to successfully build smart, efficient applications in Scala that can be compiled to the JVM.

Functional Design Patterns


In this section, we are moving beyond the basic concepts behind functional programming and looking at some of the functional design patterns that you'll encounter when using functional libraries. You will be introduced to Monoids, Functors, Monads, and other functional programming patterns that you can use to structure your programs – these patterns are the functional programming equivalent of the object-oriented design patterns that you might be familiar with from when you first learned about OOP.

Have you ever heard of category theory? The patterns we'll see in this section come from category theory. Each concept (such as a Monoid) has a clear mathematical definition and set of associated laws.

Note

In this section, we won't go into detail regarding these laws, but should you want to research this topic further, it's good to know that the field is called category theory.

This will set you up for further study of functional design patterns and enable you...
