Description

Learn how functional programming can help you in deploying web servers and working with databases in a declarative way

Key Features

  • Learn functional programming from scratch
  • Program applications with pure functions to rule out side effects
  • Gain expertise in working with array tools for functional programming

Book Description

Functional programming is a paradigm specifically designed to deal with the complexity of software development in large projects. It helps developers to keep track of the interdependencies in the code base and changes in its state in runtime. Mastering Functional Programming provides detailed coverage of how to apply the right abstractions to reduce code complexity, so that it is easy to read and understand.

Complete with explanations of essential concepts, practical examples, and self-assessment questions, the book begins by covering the basics such as what lambdas are and how to write declarative code with the help of functions. It then moves on to concepts such as pure functions and type classes, the problems they aim to solve, and how to use them in real-world scenarios. You’ll also explore some of the more advanced patterns in the world of functional programming such as monad transformers and Tagless Final. In the concluding chapters, you’ll be introduced to the actor model, which you can implement in modern functional languages, and delve into parallel programming.

By the end of the book, you will be able to apply the concepts of functional programming and object-oriented programming (OOP)in order to build robust applications.

What you will learn

  • Write reliable and scalable software based on the principles of functional programming
  • Explore advanced functional concepts such as lambdas, generic type parameters, and higher-order functions
  • Effectively solve complex architectural problems
  • Avoid unwanted outcomes such as errors or delays and focus on business logic
  • Write parallel programs in a functional style using the actor model
  • Use functional data structures and collections in your day-to-day work

Who this book is for

If you are from an imperative or OOP background, this book will guide you through the world of functional programming, irrespective of which programming language you use.
