Preface

Scala, despite being a general purpose JVM-based language like Java, provides an edge with functional programming primitives. Scala has a rich type system, which makes it more expressive. Using type systems, developers can write applications that are less error prone at runtime. Once you have spent enough time learning and practicing concepts, working with Scala is fun. Rich constructs and abstractions have made it powerful, and even framework and library developers enjoy working with Scala.

Keeping these points in mind, this book provides you with all the essentials you need to write programs using Scala. It has all the basic building blocks someone new to Scala might want to know about it, along with the reasons for using it. One of the major goals of this book is to enable you to choose a particular construct above another.

This book will be a companion on your journey towards learning and writing good software using Scala. We believe it'll be a fun journey for you all.
