This easy-to-use, fast-moving tutorial introduces you to functionalprogramming with Haskell. You'll learn how to use Haskell in avariety of practical ways, from short scripts to large anddemanding applications. Real World Haskell takes youthrough the basics of functional programming at a brisk pace, andthen helps you increase your understanding of Haskell in real-worldissues like I/O, performance, dealing with data, concurrency, andmore as you move through each chapter.With this book, you will:
Understand the differences between procedural and functionalprogramming
Learn the features of Haskell, and how to use it to developuseful programs
Interact with filesystems, databases, and network services
Write solid code with automated tests, code coverage, and errorhandling
Harness the power of multicore systems via concurrent andparallel programming
You'll find plenty of hands-on exercises, along with examples ofreal Haskell programs that you can modify, compile, and run.Whether or not you've used a functional language before, if youwant to understand why Haskell is coming into its own as apractical language in so many major organizations, Real WorldHaskell is the best place to start.
