Unit 7. Practical Haskell

Welcome to the last unit of Get Programming with Haskell! By this point, you’ve come a long way from learning the basics of referential transparency and the benefits of functional programming. This last unit is different from most of the others. The goal of unit 7 is to ease the transition from learning Haskell to writing real-world code. I’ve often found that many students of Haskell (myself included) find the transition from reading about Haskell to writing everyday code in Haskell to be more challenging than expected.

To ease this transition, this unit will ensure that you have some familiarity with a range of tasks that provide a solid foundation for building larger and more complex programs. You’ll start by learning how Haskell handles errors and will then be introduced to a useful type called Either.
