This book gets you started with essentials of software development by guiding you through various aspects of Scala programming, helping you bridge the gap between learning and implementing. You will learn about the unique features of Scala through diverse applications and experience simple yet powerful approaches for software development.
This book covers the following exciting features:
- Build, test, and package code using Scala Build Tool
- Decompose code into functions, classes, and packages for maintainability
- Implement the functional programming capabilities of Scala
