Scala is a statically typed language with a very expressive type system which enforces abstractions in a safe yet coherent manner. All values in Scala are Java objects (primitives which are unboxed at runtime), because at the end of the day, Scala runs on the Java JVM. Scala enforces immutability as a core FP principle. This enforcement happens in multiple aspects of the Scala language, for instance, when you create a variable, you do it in an immutable way, when you use an collection, you will use a immutable collection. Scala also lets you use mutable variables and mutable structures, but by design, it favors immutable ones.

Overview of this book
<p>Scala is known for incorporating both object-oriented and functional programming into a concise and extremely powerful package. However, creating an app in Scala can get a little tricky because of the complexity the language has. This book will help you dive straight into app development by creating a real, reactive, and functional application. We will provide you with practical examples and instructions using a hands-on approach that will give you a firm grounding in reactive functional principles.</p>
<p>The book will take you through all the fundamentals of app development within Scala as you build an application piece by piece. We’ve made sure to incorporate everything you need from setting up to building reports and scaling architecture. This book also covers the most useful tools available in the Scala ecosystem, such as Slick, Play, and Akka, and a whole lot more. It will help you unlock the secrets of building your own up-to-date Scala application while maximizing performance and scalability.</p>
