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.

Took it as a seasoned C++ programmer to give me another perspective and really enjoyed learning to think differently. The material was carefully prepared and the pace and exercises were great.

What an amazing course. The intensity required for the contents and exercises increases every week. I must say, I am more comfortable using and talking about Scala than I was a few weeks back.

Excellent place to start learning Scala, presuming you have some familiarity with programming. The material is probably a bit too challenging for people who have never worked with code before.

Great course on introducing functional programming. I am new to FP, but I feel I can think in a "functional" after about half of the course. It is a very instructive introduction course on FP.

Very good course with some challenging exercises. It served more as a refresher and practice tool for me as I was already deep into Scala before taking this. Nevertheless, very happy I did it.

A really great introduction to Scala, grounded in a solid and time-tested functional curriculum. As someone with a fair amount of experience, this helped me come up to speed in Scala quickly.

Amazing. Very useful how it started off throwing you into the deep end with recursion, to help jar your mind, opening it to functional.... for those of us who coded imperative for many years

Great work, great pedagogy. I really enjoyed learning Scala principles. The proposed exercices are really challenging, and very well constructed. Thanks a lot for this MOOC. Thank you Martin.

The best part is the assignments, which make you think in a more pragmatic and functional manner, something that is not really straightforward for people coming from an object-oriented world.

Pace of progression of concepts was just right. You may need to spend more time with the course than what is suggested. I found myself spending more than 3hrs on the assignments consistently.

A very detailed and thorough explanation accompanied with a very apt set of assignments - and the plus point is that it all comes from the creator of SCALA himself. What can one ask for more?

Excellent course! I would have liked to see a brief discussion/digression of anonymous classes and their usage. I also found the recommended reading to build nicely on the concepts presented.

This is a great course for learning Functional Programming language. All the course content including Assignments are up to the mark. I thank the tutors for providing such great information.

Muy bueno el curso, hace un repaso importante por el lenguaje. Me gusto mucho los ejemplos y los momentos donde se tomaba el tiempo para programar junto a uno y mostrar las funcionalidades.

Imaginative and challenging course. You may feel your brain melt (or even break) as you try to adapt it to the functional programming mindset, but ultimately you will be the smarter for it.

This course has already changed how I code (even when I'm using languages that are not Scala). It has really opened my mind to a new way of thinking. Thank you to the makers of the course.

Ever heard about (Ever heard about (Ever heard about (Ever heard about (recursion?)))). If you're looking for a course on the fundamentals of functional programming, this is a nice choice.

It's awesome lecture!

I already use Scala but the lectures are useful for further comprehension of the language.

Although I needed to relearn high school's math like Mathematical induction.

Fantastic teaching and some very challenging exercises! It gives you a really great tool kit and some very useful source to refer to. Very good fun and a big thank you to the team at EPFL.

This is changing the way you used to think about programming, forcing yourself to not mutate state, to trade loops for recursion is super strange and has some sick pleasure attached to it

A very informative and in-depth introduction to FP and Scala. The Scala part is okay if you already know some other programming languages, but the FP part is delightful and not that easy.

Must have introduction to Scala. Odersky is great lecturer and I enjoyed the course greatly, but some lectures were hard to follow and the first and the last assignment were quite hard...

Very good, inspiring introduction to Scala. I recommend to everyone interested functional programming or Scala. I would say it was a bit hard, but eventually when I made it, I was happy!

I have been developing applications on a scala more that year and have taken a course to structure and evaluate my knowledges. Highly recommend for beginners and experienced developers.
