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.

This course has been very helpful for learning monads and how they relate to reactive programming.

Great course! Once they work out the bugs with grading the calculator project it will be 5 stars.

Very good course.

Automated correction tool could do with more verbosity on failed test cases.

I feel that the lectures need more detailed discussions about the scala design pattern.

Good course.

Next step to get specialization in Scala and FP.

Many thanks, Pavel

FRP is interesting, but the Future seems lack of explanation and homework

Video material is a little bit confusing. It reminds me patchwork quilt

Some exercises to practice previous to the exam can be great I guess.

很好 ,但是因为又删减,所以感觉不是那么连贯。所以四星吧。比如最后一章,其实内容很深远,但是作业却没有考察到课程所说的内容。
