Haskell Fundamentals (4-Day Course) with Alejandro Serrano

HASKFNDM4D-AS-02

  4 days

English  

Gain a solid understanding of the fundamental concepts of Haskell, a powerful functional programming language, in this introductory course with Alejandro Serrano.

Haskell is an advanced open source language that’s purely functional. It features concise built-in concurrency and parallelism, thousands of libraries, and a rich ecosystem making it a valuable tool for any programmer.

Learn the basic concepts, techniques of this mathematical-based language, change the way you think about programming, and start developing concise programs with increased type safety.

Advanced Kubernetes Concepts with Jérôme Petazzoni

This in-depth course combines virtual classroom lectures and hands-on guided exercises designed to introduce attendees to all the concepts, ideas, techniques, and libraries that they’ll need to start developing their first programs in Haskell.


This course is run virtually over 4 half‑day sessions.

Our virtual courses offer the same expert-led, hands-on experience we've offered since 2013 — accessible from the comfort of your own home (office).

You’ll join Alejandro and participants from around the globe in a virtual classroom where you’ll utilize collaboration tools like Zoom and Slack to learn, discuss, and get hands-on with in-depth exercise sets. By the end of day one, you’ll be developing a small server that takes and responds to JSON requests.

Please note, this event runs over 4 days on Mondays, Tuesdays, Thursdays and Fridays. There is no class on Wednesdays.

Course Outline

Simple Constructs
  • Simple definitions
  • Definitions using pattern matching and guards
  • Local bindings with let and where
  • Pattern matching over lists, recursion
  • Higher-order functions: maps and folds
  • Anonymous functions and partial application
Algebraic data types and type classes
  • Record types, and record syntax
  • Enumerations
  • General shape of algebraic data types
  • Differences from OOP modeling
  • Polymorphic types: lists, trees
  • First-order type classes: Eq, Ord, Show
  • Automatic derivation
Input/output
  • Concept of purity and tagging with IO
  • Do blocks: pure vs. impure values

  • Small introduction to streaming
Functional error handling
  • Maybe and Either as polymorphic types
  • Combinators to work on the happy path
  • Dealing with errors in IO: exceptions
Higher-kinded type classes: Functor and Monad
