![]() That’s the driving desire that leads them to use only pure functions and immutable values, because that’s what you use in algebra and other forms of math.įunctional programming is a large topic, and there’s no simple way to condense the entire topic into this little book, but in the following lessons we’ll give you a taste of FP, and show some of the tools Scala provides for developers to write functional code. ![]() In that regard, you could say that functional programmers like to think of themselves as mathematicians. #Scala programming code#Code Snippets: copy-paste friendly versions of every code snippet in the book. #Scala programming series#As Alvin Alexander wrote in Functional Programming, Simplified, rather than using that description, it can be helpful to say that functional programmers have an extremely strong desire to see their code as math - to see the combination of their functions as a series of algebraic equations. This repository is the online hub for the book Hands-on Scala Programming: Chapter Notes, Errata, and Discussion: go here if you want to leave comments or ask questions about individual chapters. So, you can not only construct elegant class hierarchies for maximum. Programming Scala clearly explains the advantages of Scala as a JVM language. The combination of both styles in Scala makes it. ![]() But because the FP style is still relatively new to many developers, we’ll provide a brief introduction to Scala’s support for FP in the next several lessons.įunctional programming is a style of programming that emphasizes writing applications using only pure functions and immutable values. Scala school started as a series of lectures at Twitter to prepare experienced engineers to be productive Scala programmers. The biggest strength of Scala is that it provides a beautiful blend of object-oriented programming and Functional programming. With this book, youll discover why Scala is ideal for highly scalable, component-based applications that support concurrency and distribution. Scale is a blend of object-oriented and functional programming concepts in a statically typed language. This book assumes that you’re coming to Scala from an OOP language like Java, C++, or C#, so outside of covering Scala classes, there aren’t any special sections about OOP in this book. Scala lets you write code in an object-oriented programming (OOP) style, a functional programming (FP) style, and even in a hybrid style, using both approaches in combination. Scala is a general-purpose, high-level, multi-paradigm programming language. What is Scala Programming Scala is a portmanteau of ‘scalable’ and ‘language’. ![]()
