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....

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.

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!

The grading seems to round up to 100%, which makes the assignments that are already generally easy far too easy. I took this course instead of just doing my own thing so that I could get some structure and motivation. While there was some structure, it was quite basic, and the motivation was diminished by "good enough" not being much. I was considering taking the later courses in the specialization, but I'm afraid that without real grading I won't learn as much as if I learn more slowly outside of Coursera.

Great content but the rhythm is a bit fast, I didn't feel fully equipped to manage exams, indeed, each of them took me at least 2 days to solve and I have rage quit for a complete week for the last exam. I'm going to redo some of them before start the second course.

Apart from that, the format is cool and it's pleasant to watch the teacher solving the rare mistakes he did with ease.

I really feel that the assignments were out of sync with the content of the lectures. Occasionally it seems that you needed to watch all the videos in order to go back and complete assignments that should have been done already. It was very confusing without a background in the material. I liked the lecture material a lot, but feel the assignments should have been more connected.

The assignments took me so long. It was supposed to be 3 hours but, got obsessed to have them ended ok, but in 15 hours nearly. I would recommend to build up from very basic stuff, and as the learning advances, going into more difficulty.

The hints for the assignments were valid in the the last lesson, but for another lesson, I think lesson 4, there was no hint.

If looking only at what is being taught in this course, it's quite good. And I can heartily recommend it.

The lecture videos are extremely monotonic! Which makes it _very_ hard to keep focus and pay attention. It feels like hypnosis sometimes. Several colleagues have the same experience with this course. Which is why I'm only giving it 3 stars.

The points covered are interesting and useful, with an insight on Functional Programming. However, for newcomers on functional programming, the assignments are a bit too far from the videos or lack the instructions needed to complete them in 3 hours. Some hints for the toughest parts would be very much appreciated.

1)lecture slides in text format would be a great thing - to review smth you have to scroll through the video every time

2) some of the content is outdated - there are a lot of method demonstration that are currently deprecated

3) It would be great to see Java vs Scala syntax comparison more

The course is not really about Functional Programming, but more about Scala in general. I've learnt much more about FP by reading Learn You a Haskell for Great Good by Miran Lipovača, and Functional Programming in Scala by Paul Chiusano and Rúnar Bjarnason

The only attractive thing in this course is a name of the author. The course itself is poorly designed, homework is hardly connected to the content of lectures. Might be interesting as an introduction for Scala newcomers, though.

Instead of teaching Scala syntax, it focuses on teaching functional programming logic and conventions, which makes it a very challenging course. If you are looking for an introduction to Scala, this is not it.

P​oderia focar mais em funcional e explicar melhor... conteudo esparso e denso com poucos exemplos prtáicos.... senti bastante dificuldade, se noã fossem alguns livros eu noã entenderia bem o scala.

after python very difficult. would be good with explaining for IDE using instead of just reading

I have the feeling that Scala is a language that may have a nice logical consistency, but is far too much overloaded with symbols and possibilities for achieving exactly the same thing in different ways. I think you can appreciate this course if you have a background in theoretical computer science, but for all others who choose the course to learn Scala as a language without academic interest, that is just confusing.

A Scala beginner can also not appreciate how elegant and concise the produced code is and that you can put the meaning of hundreds of lines of imperative code into only a few lines of functional code (without side-effects!). For a beginner, it is more important that you can still read and understand your own code two weeks after finishing this course.

From other coursera courses, I am used to getting the course material (slides, example code) as a download, either linked in every week's curriculum or in the course overview resources section. For this course, I was not able to find it and have manually typed the exercises during the lectures. If it is actually there and I just could not find it, consider this statement pointless.

Concerning the tools setup, I have the impression that the descriptions in the beginning of the course are very detailed, however quite outdated. I ended up following a guide on installing sbt from here and have used it with Visual Studio code.

Another thing that I at least did not catch in this course was how to actually create, deploy and run a simple Scala command line application. Do all people ever just use the IntelliJ IDE worksheets? The problem could also be that I do not have a Java background and am missing some knowledge that is obvious to all others.

I've tried to take the course and have already completed 3 assignments. I have to say that I still do not understand how to code basic stuffs on scala. Going to unenroll from the course. The course is too technical, no syntax was explained, given that I do not have any background from scala, this course is poorly presented. Most of the assignments are algorithm based, although it is not too hard to me (3 hours assignment but I am able to finish it within 1 hour), but the course is not enjoyable.

I expected something different from a "Principles" course. It is expected to have a Computer Science background and the assignments are not easy at all. I mean, they don't need to be stupid, but they can be really frustrating for a novice (since i thought this course was for novice students). Lessons are ok, but i really hate that the teacher doesn't give the examples and you have to write them by your own, slowing down the pace of your learning.

It is mentioned that it is only necessary to have at least one year of experience in a programming language, however, it does not mention that you must have a solid base in arithmetic, all the examples are associated in a very general way but with great complexity that is not clarified. The assigned tasks are becoming more complex. All prerequisites to enter the course should be declared.

There is a big disconnect between lectures and assignments. It seems like there is a mix and mash of materials from different sources. Had the instructor and EPFL team put more efforts into the support resources, it could have been much better. I really liked the videos from Weeks 1 and 2, but then the later week videos seemed inconsistent.

This course was too theoretical, for my taste. Many lectures looked like an advanced mathematics course. Also, the course tasks were way too hard for someone just starting with the language. My senior colleagues at work said, that if their learning of Scala would have started this way, they would have ran away and never returned back.

I have a proficiency in Python and R and I think it is very difficult to use the ItelliJ for the first time. I would like some guidence in order to know how to use correctly the IDE. I get so many errors and I do not know what does so many things about programming in this lenguage or Java. A bit dissapointed...

Although the explanation is well done in the videos, the complexity of the submission excercises is crushing. Besides you never know how it is properly done. There is nothing that guarantees that you are doing the right thing. This course is not for 100% beginners in scala. Terrible experience

Most basic setup instructions for the dev environment do not work as described or at all. Linked external instructions are not clear. I would have been better off trying to learn FP in Scala on my own.

too much academic and outdated (2012 year of release, if i am not mistaken) . The book "Programming in Scala" written the same author is much better, because the author updates the book.

T​he course doesnt provide the necessary information to complete the assignments. Too heavy on algorithms solving instead of teach functional programming.
