About the Course

In this course you will learn how to apply the functional programming style in the design of larger Scala applications. You'll get to know important new functional programming concepts, from lazy evaluation to structuring your libraries using monads. We'll work on larger and more involved examples, from state space exploration to random testing to discrete circuit simulators. You’ll also learn some best practices on how to write good Scala code in the real world. Finally, you will learn how to leverage the ability of the compiler to infer values from types. Several parts of this course deal with the question how functional programming interacts with mutable state. We will explore the consequences of combining functions and state. We will also look at purely functional alternatives to mutable state, using infinite data structures or functional reactive programming. Recommended background: You should have at least one year 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 with using the command line. This course is intended to be taken after Functional Programming Principles in Scala:

This course is OK as a successor of "Functional Programming Principles in Scala". You definitely learn a lot of new functional concept, the material is presented well and the homework is engaging (though it is debatable if it couldn't be more closely related to the course content).

Participants should know, though, that this is a condensed version of a previous Coursera course by the same authors, "Principles of Reactive Programming", which is no longer available. Compared to the earlier course, the present course is less coherent – it consists more or less of a subset of the earlier course’s lectures (videos). As a consequence, the instructors sometimes refer to earlier or later lectures that are not actually there (or at least not in the expected order). (I recommend participants to look up the missing lectures on Youtube:

Lastly, I do not think the title "Functional Program Design" is appropriate. I would call it "Elements of Reactive Programming in Scala" or something similar.
