Becoming Functional (Joshua Backfield) (Z-Library)

Author：Joshua Backfield

If you have an imperative (and probably object-oriented) programming background, this hands-on book will guide you through the alien world of functional programming. Author Joshua Backfield begins slowly by showing you how to apply the most useful implementation concepts before taking you further into functional-style concepts and practices. In each chapter, youll learn a functional concept and then use it to refactor the fictional Xxy companys imperative-style legacy code, writing and testing the functional code yourself. As you progress through the book, youll migrate from Java 7 to Groovy and finally to Scala as the need for better functional language support gradually increases.
