A significant part of the work of a developer is to minimize the amount of code duplication. There are multiple different approaches to do this, including inheritance, abstraction, generics, type classes, and so on. There are cases, however, where strongly typed languages will require some extra work in order to minimize some of the duplication. Let's imagine that we have a method that can read and print the contents of a file. If we have two different libraries that allow us to read a file, in order to use our method, we will have to make sure the methods that read the file somehow become the same type. One way would be by wrapping them in a class that implements a specific interface. Provided that in both the libraries the read method has the same signature, which could easily happen, Scala can use duck typing instead, and this way it will minimize the extra...

Overview of this book
Design patterns make developers’ 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’ll learn about the various features of Scala and will 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 and latest features of Scala while using practical real-world examples. We will be learning about IDE’s and Aspect Oriented Programming. We will be looking into different components in Scala. We will also cover the popular "Gang of Four" design patterns and show you how to incorporate functional patterns effectively. The book ends with a practical example that demonstrates how the presented material can be combined in real-life applications. You’ll learn the necessary concepts to build enterprise-grade applications.
By the end of this book, you’ll have enough knowledge and understanding to quickly assess problems and come up with elegant solutions.
