Haskell is a deep language; we think learning it is a hugely rewarding experience. We
will focus on three elements as we explain why. The first is novelty: we invite you to
think about programming from a different and valuable perspective. The second is
power: we’ll show you how to create software that is short, fast, and safe. Lastly, we
offer you a lot of enjoyment: the pleasure of applying beautiful programming techniques
to solve real problems.
This easy-to-use, fast-moving tutorial introduces you to functional programming with Haskell. You'll learn how to use Haskell in a variety of practical ways, from short scripts to large and demanding applications. Real World Haskell takes you through the basics of functional programming at a brisk pace, and then helps you increase your understanding of Haskell in real-world issues like I/O, performance, dealing with data, concurrency, and more as you move through each chapter. With this book, you will:
Understand the differences between procedural and functional programming
Learn the features of Haskell, and how to use it to develop useful programs
Interact with filesystems, databases, and network services
Write solid code with automated tests, code coverage, and error handling
Harness the power of multicore systems via concurrent and parallel programming
You'll find plenty of hands-on exercises, along with examples of real Haskell programs that you can modify, compile, and run. Whether or not you've used a functional language before, if you want to understand why Haskell is coming into its own as a practical language in so many major organizations, Real World Haskell is the best place to start.
