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 is a university degree course which takes enormous effort to complete. But still its beond the programming course range giving you whats not possible to google or learn practical way. Thanks!

Thank you for this exciting course! I did the FP in Scala course a few years ago and decided to do the full certification now. I am looking forward to the next courses in the specialisation.

Not as good as the first one, esp near the end.

Worse than Scala Principles - too chaotic.

The old version was more interesting.

Subjects of exams are really cool but they are already written at 80~90%, I would prefer to have to do things from scratch even if the subject is less interesting. A part from that, there no connecting thread during the course, each weeks is about something new and we don't really use stuff from the previous week. Globally, it's hard to retain the new knowledge...

This course will shatter your desire to learn Scala. I recommend you use it as a means to test how much you really know AFTER learning Scala from another resource. The videos are old and the staff will not help you even though there is such little time to finish each assignment.

The concepts are not explained clearly. I need to take help from other websites to understand them.

The example was also not complete, just a theory without running code.
