Build applications quicker and with less effort using functional programming and Kotlin. Learn by building a complete application, from gathering requirements to delivering a microservice architecture following functional programming principles. Learn how to implement CQRS and EventSourcing in a functional way to map the domain into code better and to keep the cost of change low for the whole application life cycle. If you're curious about functional programming or you are struggling with how to put it into practice, this guide will help you increase your productivity composing small functions together instead of creating fat objects. Switching to the functional paradigm isn't easy when you're used to object-oriented programming. You need more than just lambdas and mapping over collections to get a declarative style and disentangle the state from the computations. Use transformations and compositions to help you write less code with better results. Boost your productivity and harness the power of functional programming by creating real-world applications rather than focusing on theoretical concepts. Work through a series of short exercises to find and compose pure functions, and create data structures that work like algebra. Get rid of mutable state in your software to eliminate the main source of bugs. Apply CQRS and EventSourcing patterns to translate stakeholder requirements into functional design and then into code. See how Kotlin's easy-to-learn syntax and functional-friendly approach make it a great option for a pragmatic language that integrates well with existing Java code and libraries. Leverage functional programming to build and deliver robust applications in less time and with fewer defects. What You Need: The code in this book is designed to allow you to build your application from scratch on Windows, Mac and Linux. You will need a recent IDE, we recommend IntelliJ Community Edition, and Kotlin 1.3.x or later.

This book aims to show how programming will be changed by the concepts of parallel systems and how these concepts relate to the ideas of functions and objects. To demonstrate the kind of programming that can be done on these systems, the research language Balinda K is used. The book will also enhance the reader's grasp of the concepts of concurrency and modular programming, reviewing these from the perspectives of application programming in a parallel language. The book should interest graduate and senior undergraduate students of computer science and computer engineering, and IT professionals working in a multiprocesing or distributed computing environment.

JavaScript brings functional programming to the mainstream and offers a new way of doing object-oriented programming without classes and prototypes. Programming in a functional style means using concepts such as first-class functions, closures, higher-order functions, partial application, currying, immutability, or pure functions. Functional programming promises to make code easier to read, understand, test, debug, or compose. Can we build an application using only pure functions? Decorators are a tool for reusing common logic and creating variations of existing functions. Closure can encapsulate state. Multiple closures sharing the same private state can create flexible and encapsulated objects. "One of the best new Functional Programming ebooks" - BookAuthority

Object Oriented Programming in C++Object Oriented Programming is a programming in which we design and develop our application or program based of object. Objects are instances(variables) of class.Object oriented programming does not allow data to flow freely around the system. It binds data more closely to the functions that operate on it, and protects it from accidental modifications from outside functions.Object oriented programming allows separation of a complex programs into objects and then builds data and functions around these objects. The data of an object can be accessed only by the functions associated with that object. However, functions of one object can access the functions of other objects.Features of OOP's ( Object Oriented Programming ) Class: Class is an encapsulation of data and coding. Classes are an expanded version of structures. Structure can contain multiple variables. Classes can contain multiple variables, even more, classes can also contain functions as class member. Variables available in class are called Data Members. Functions available in class are called Member Functions. Object: Class is a user-defined data type and object is a variable of class type. Object is used to access class members. Inheritance: Inheritance means access the properties and features of one class into another class. The class who is going to provide its features to another class will be called base class and the class who is using the properties and features of another class will be called derived class. Polymorphism: Polymorphism means more than one function with same name, with different working. It can be static or dynamic. In static polymorphism memory will be allocated at compile time. In dynamic polymorphism memory will be allocated at runtime. Both function overloading and operator overloading are an examples of static polymorphism. Virtual function is an example of dynamic polymorphism. Data Abstraction: The basic idea of data abstraction is to visible only the necessary information, unnecessary information will be hidden from the outside world. This can be done by making class members as private members of class. Private members can be accessed only within the same class where they are declared. Encapsulation: Encapsulation is a process of wrapping data members and member functions in a single unit called class. Using the method of encapsulation, the programmer cannot directly access the data. Data is only accessible through the object of the class.

Master functions and discover how to write functional programs in R. In this concise book, you'll make your functions pure by avoiding side-effects; you’ll write functions that manipulate other functions, and you’ll construct complex functions using simpler functions as building blocks. In Functional Programming in R, you’ll see how we can replace loops, which can have side-effects, with recursive functions that can more easily avoid them. In addition, the book covers why you shouldn't use recursion when loops are more efficient and how you can get the best of both worlds. Functional programming is a style of programming, like object-oriented programming, but one that focuses on data transformations and calculations rather than objects and state. Where in object-oriented programming you model your programs by describing which states an object can be in and how methods will reveal or modify that state, in functional programming you model programs by describing how functions translate input data to output data. Functions themselves are considered to be data you can manipulate and much of the strength of functional programming comes from manipulating functions; that is, building more complex functions by combining simpler functions. What You'll Learn Write functions in R including infix operators and replacement functions Create higher order functions Pass functions to other functions and start using functions as data you can manipulate Use Filer, Map and Reduce functions to express the intent behind code clearly and safely Build new functions from existing functions without necessarily writing any new functions, using point-free programming Create functions that carry data along with them Who This Book Is For Those with at least some experience with programming in R.

You want increased customer satisfaction, faster development cycles, and less wasted work. Domain-driven design (DDD) combined with functional programming is the innovative combo that will get you there. In this pragmatic, down-to-earth guide, you'll see how applying the core principles of functional programming can result in software designs that model real-world requirements both elegantly and concisely - often more so than an object-oriented approach. Practical examples in the open-source F# functional language, and examples from familiar business domains, show you how to apply these techniques to build software that is business-focused, flexible, and high quality. Domain-driven design is a well-established approach to designing software that ensures that domain experts and developers work together effectively to create high-quality software. This book is the first to combine DDD with techniques from statically typed functional programming. This book is perfect for newcomers to DDD or functional programming - all the techniques you need will be introduced and explained. Model a complex domain accurately using the F# type system, creating compilable code that is also readable documentation---ensuring that the code and design never get out of sync. Encode business rules in the design so that you have "compile-time unit tests," and eliminate many potential bugs by making illegal states unrepresentable. Assemble a series of small, testable functions into a complete use case, and compose these individual scenarios into a large-scale design. Discover why the combination of functional programming and DDD leads naturally to service-oriented and hexagonal architectures. Finally, create a functional domain model that works with traditional databases, NoSQL, and event stores, and safely expose your domain via a website or API. Solve real problems by focusing on real-world requirements for your software. What You Need: The code in this book is designed to be run interactively on Windows, Mac and Linux.You will need a recent version of F# (4.0 or greater), and the appropriate .NET runtime for your platform.Full installation instructions for all platforms at fsharp.org.

The papers in this volume examine the current role of grammatical functions in transformational syntax in two ways: (i) through largely theoretical considerations of their status, and (ii) through detailed analyses for a wide variety of languages. Taken together the chapters in this volume present a comprehensive view of how transformational syntax characterizes the elusive but often useful notions of subject and object, examining how subject and object properties are distributed among various functional projections, converging sometimes in particular languages.
