Functional Programming Demystified: Write Elegant Code with Haskell, Elixir, and JavaScript

Unleash the full power of functional programming and revolutionize the way you build backend systems.

In Functional Programming Demystified, you'll go beyond theory and dive into real-world application using three powerful languages-Haskell for mathematical precision, Elixir for scalable concurrency, and JavaScript for cross-platform flexibility. Whether you're a backend developer looking to adopt FP principles or a seasoned engineer seeking to improve code clarity, this book is your ultimate roadmap.

What You'll Learn:

• Master immutable data structures and pure functions to build bug-resistant applications.

• Leverage pattern matching, monads, and type inference in Haskell for expressive, type-safe programming.

• Harness OTP, actor models, and message-passing concurrency in Elixir for fault-tolerant web services.

• Apply functional pipelines, closures, and first-class functions in JavaScript for clean, modular logic.

• Build RESTful APIs with stateless architecture using FP principles.

• Integrate with real-time systems and event-driven design for reactive programming at scale.

• Refactor legacy codebases with function composition, higher-order functions, and currying.

• Implement microservices and functional domain modeling to design scalable backend ecosystems.

Perfect for:

• Software engineers transitioning to FP

• Backend developers focused on scalability and performance

• Programmers aiming to improve code maintainability and testability
