Real World Haskell

Book Description
This easy-to-use, freely available online, fast-moving tutorial introduces you to functional programming with Haskell. Learn how to use Haskell in a variety of practical ways, whether it's for short, script-like programs or large and demanding applications. Written for experienced programmers, Real World Haskell takes you through the basics of functional programming at a brisk pace, and 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 difference between procedural and functional programming
• Learn about Haskell's compiler, interpreter, values, simple functions, and types
• Find your way around Haskell's library -- and write your own
• Use monads to express I/O operations and changes in state
• Interact with databases, parse files and data, and handle errors
• Discover how to use Haskell for systems programming
• Learn concurrency and parallel programming with Haskell

You'll find plenty of hands-on exercises, along with examples of real Haskell programs that you can modify, compile, and run. If you've never used a functional language before, and want to understand why Haskell is now coming into its own as a practical language in so many major organizations, Real World Haskell is the place to start.
