About the Course

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 background in mathematics (e.g., algebra, logic, proof by induction). Last, you should have some familiarity with using the command line....

It took me much longer than expected to finish the course and sometimes it made me feel stupid and helpless. Diving into functional programming was a mind bending experience, totally worth time spent!

Really good explanation by the instructor. Good assignments. The assignments gave a good insights into functional programming. I loved the way the problems were decomposed into neat smaller functions.

This was a decent overview of FP principals, but a poor introduction to the Scala language. In fact, the requirements should just come out and state that you must have prior Scala knowledge to most thoroughly appreciate the course. The last 2 assignments may have been ok for 3 hours (doubtful) for someone with Scala experience, but they really should be marked more appropriately for time for those of us new to Scala. I'd say 6 hours; easily more than that for the last assignment.

Also, no slides or related handouts are provided. If you remember seeing something on one of the slides shown, you'll have to look back, scanning through all the videos trying to find it. This is a very poor way to manage course content - forcing students to rely solely on the videos.

I'm left feeling I've only learned a smattering here and there of Scala, and don't think I'll take the remainder of the specialization as I had intended.

This is a reasonably thorough introduction to the principals of functional programming in scala, but to fully grasp the material presented I found it necessary to include supplemental material such as the functional programming in scala book by Paul Chiusano (forward by the course instructor funnily enough). One point of frustration however was the near total unavailability of the course TA's or instructor. Also because the only forum for interacting with them is entirely public it's impossible to receive any formal code review apart from the automated tests they run when you submit. There were multiple occasions where I wanted feedback on not just the technical correctness of my solution but also to know if there might have been a more idiomatic or generally efficient (read: tail-recursive) way to express some peculiar bit of logic.
