The Problem of Side Effects

Pure functional programming is all about removing side effects and mutations. We remove them for a reason. In this chapter, we will see how shared mutable states and side-effecting functions can cause problems and why it is best to reduce them.

The topics discussed are as follows:

Side effects
Mutable states
Pure functions
Generally encountered side effects
Pure functional paradigms in different programming languages

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.
