Functional Programming with Haskell

Course Program

This is a draft program. It can change.

• Introduction to Functional Programming & the Haskell language. Basic concepts & syntax. Pure functions and immutability.
• Starting out with functions, type signatures & solving problems with recursion. Difference between types and typeclasses.
• (x:xs) - Lists & Problems with lists. Pattern matching.
• Higher order functions - the complete package. maps, filters and folds.
• Currying, Partial function applications & function composition. (.) and ($).
• Haskell's type inference & lazy evaluation - examples. Strictness & Non-Strictness
• Making our own types & typeclasses.
• Input / Output & making some console tools with Haskell.
• Introduction to Haskell's real world tools - Cabal. How to install 3rd party libraries & make projects.
• Consuming HTTP & parsing / crawling websites with wreq and tagsoup
• Making simple HTTP servers with Scotty or Yesod
• Looking things from the abtract point of view - starting with the typeclasses for Functors and Applicative Functors.
• Raising up the abstraction level - Associative binary functions, identities and monoids.
• return does not return what you think it returns! Hello Monadic World.
• Looking back to the libraries we have used with the newly aquired knowledge. How are they implemented? Can we do it ourselves?
