Learn Haskell by Example

Haskell Bookcamp builds your skills with production-quality Haskell code by creating interesting projects. As you work through each application, you will master functional programming and dip into the language's advanced features. The book will help you learn Haskell from the ground up with real-world examples rather than tedious academic exercises. Haskell Bookcamp builds your skills with production-quality Haskell code by creating interesting projects. As you work through each application, you will master Haskell basics and functional programming and dip into the language's advanced features. Haskell's abstract concepts can be confusing—so you will learn them from the ground up with real-world examples rather than tedious academic exercises. Learn how to structure real-world applications, work with the Haskell toolchain effectively and what to look out for when writing critical sections in the programme's logic. Best of all, each project in this book is fully extensible and customisable, so you can keep tinkering with your favourites! About the reader For readers who know how to program in an object-orientated language. Learn Haskell by doing Haskell projects! For readers who know how to program in an object-orientated language. Haskell Bookcamp will offer you practical experience writing Haskell code and applying functional programming to actual development challenges. You will build your Haskell skills by working through hands-on challenges and conundrums. You will learn to look at each project through a Haskell lens and then solve it using features like lazy evaluation, immutable data structures, and monads. And the projects are interesting! You will take on writing a tool for working with CSV files, creating a domain-specific language for music, an image processing library using concurrency for high performance, and more! Key features include: Use Haskell for daily programming tasks Effectively apply functional concepts Avoid common beginner pitfalls of Haskell Apply abstract concepts in the Haskell language Debug and profile Haskell applications Improve the performance of Haskell applications About the technology Haskell delivers clean and safe code with mathematical precision and certainty. The pure functional coding language lets you use high-level abstractions to keep your code clean and easily readable, actively disallowing many dangerous behaviours that lead to bugs and crashes. These features make Haskell an amazing choice for applications that need an extra guarantee of safety, such as smart contracts, data-intensive applications, and large-scale distributed systems.
