Episode synopsis

We've kicked off C9 Lectures with a journey into the world of Functional Programming with functional language purist and high priest of the lambda calculus, Dr. Erik Meijer (you can thank Erik for many of the functional constructs that have shown up in languages like C# and VB.NET. When you use LINQ, thank Erik in addition to Anders). 

We will release a new chapter in this series every Thursday.

In Chapter 4, Dr. Meijer teaches us about the art and practice of defining functions. Functions can be defined using conditional expressions and in Haskell conditional expressions must always have an else clause. Functions can also be defined using guarded equations and pattern matching. You will learn about list patterns and integer patterns. Today is also the day that you will learn about lambda expressions and sections.

You should watch these in sequence (or skip around depending on your curent level of knowledge in this domain):

Chapter 1
Chapter 2
Chapter 3

Now, we do have a textbook and you should go buy it: The great Graham Hutton's Programming in Haskell. We worked with the publisher, Cambridge University Press, to get all Niners a 20% discount on the book. Now, you don't need the book to learn a great deal from this lecture series since Graham's website has all the slides and samples from the book as well as answers to the exercises. That said, it's highly recommended reading and you should consider it.
