Scala Design Patterns

By: Ivan Nikolov

Overview of this book

Scala has become increasingly popular in many different IT sectors. The language is exceptionally feature-rich which helps developers write less code and get faster results. Design patterns make developer’s lives easier by helping them write great software that is easy to maintain, runs efficiently and is valuable to the company or people concerned. You will learn about the various features of Scala and be able to apply well-known, industry-proven design patterns in your work. The book starts off by focusing on some of the most interesting features of Scala while using practical real-world examples. We will also cover the popular "Gang of Four" design patterns and show you how to incorporate functional patterns effectively. By the end of this book, you will have enough knowledge and understanding to quickly assess problems and come up with elegant solutions.

Summary


This chapter was dedicated to some of the functional programming theories that seem to put many people off pure functional programming. Mostly, because the majority of explanations require strong mathematical background, we see people avoiding the concepts covered in this chapter.

We talked about monoids, monads, and functors, and we showed some examples of how to use them and what is the difference between having and not having them. It turns out that we use these concepts more often than we think, but we just don't realize it.

We saw that monoids, functors, and monads can be used for a variety of purposes—performance optimization, abstraction, and removal of code duplication. Properly understanding these concepts and feeling comfortable with them might take some time initially, but after some practice, developers tend to get a much better understanding and use them much more often than before. Hopefully, this chapter has made monoids, monads, and functors look much simpler than...
