Becoming Functional: Steps for Transforming Into a Functional Programmer
About this ebook
In each chapter, you’ll learn a functional concept and then use it to refactor the fictional XXY company’s imperative-style legacy code, writing and testing the functional code yourself. As you progress through the book, you’ll migrate from Java 7 to Groovy and finally to Scala as the need for better functional language support gradually increases.
- Learn why today’s finely tuned applications work better with functional code
- Transform imperative-style patterns into functional code, following basic steps
- Get up to speed with Groovy and Scala through examples
- Understand how first-class functions are passed and returned from other functions
- Convert existing methods into pure functions, and loops into recursive methods
- Change mutable variables into immutable variables
- Get hands-on experience with statements and nonstrict evaluations
- Use functional programming alongside object-oriented design
