Course Description

Functional programming is becoming increasingly widespread in industry. This trend is driven by the adoption of Scala as the main programming language for many applications. Scala fuses functional and object-oriented programming in a practical package. It interoperates seamlessly with both Java and Javascript. Scala is the implementation language of many important frameworks, including Apache Spark, Kafka, and Akka. It provides the core infrastructure for sites such as Twitter, Netflix, Zalando, and also Coursera.

In this course, you will discover the elements of the functional programming style and learn how to apply them usefully in your daily programming tasks, such as modeling business domains or implementing business logic. You will also develop a solid foundation for reasoning about functional programs, by touching upon proofs of invariants and the tracing of execution symbolically.

The course is hands-on; most units introduce short programs that serve as illustrations of important concepts and invite you to play with them, modifying and improving them. The course is complemented by a series of programming projects as homework assignments.

Recommended background: You should have at least one year of programming experience. Proficiency with Java or C# is ideal, but experience with other languages such as C/C++, Python, Javascript, or Ruby is also sufficient. You should have some familiarity using the command line.

The author's struggles with Haskell resonate. I suspect it's just a very hard language to learn. I've given up attempting to learn it at least twice now.

I took Martin Odersky's Scala MOOC sometime around 2012-2014 and it was easy. It just made sense and the IDE experience was nice. I would recommend it to anyone who uses C# or Java and wants to learn FP. Although after 8 years I don't know if it's still as good, or if something better has come along. Either way, the course is still available:

Next I worked through SICP and that was the best CS book I've read, although significantly more difficult than the Scala course.

Note that the course got revamped this year. It is now based on Scala 3 and new content was added. Some of the new topics are: enums, extension methods, and givens.
