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: https://www.coursera.org/learn/progfun1.

What's inside
Syllabus
For Expressions and Monads
We'll start by revisiting some concepts that we have learned from Principles of Functional Programming in Scala; collections, pattern matching, and functions. We'll then touch on for-comprehensions, a powerful way in Scala to traverse a list, process it, and return a new list. We'll see how to do queries with for-comprehensions as well as how the for-comprehension is "desugared" into calls to higher-order functions by the Scala compiler. Finally, we'll discuss what monads are, and how to verify that the monad laws are satisfied for a number of examples.

Lazy Evaluation
This week we'll revisit performance issues caused by combinatorial search, and we'll discover an important concept in functional programming that can address these issues: laziness. We'll also learn a little bit about proofs on trees; in particular, we'll see how to extend structural induction to trees.
Type-Directed Programming
This week, we’ll learn how to make the compiler write programs for us! We’ll see how the compiler can summon program fragments based on their type and how this mechanism can be used to implement a new form of polymorphism (type classes).
Functions and State
This week, we'll learn about state and side-effects. Through a rich example, we'll learn programming patterns for managing state in larger programs. We'll also learn about for-loops and while-loops in Scala.
Timely Effects
This week we'll learn a number of important programming patterns via examples, starting with the observer pattern, and then going on to functional reactive programming.

Reviews summary
Functional program design in scala
Learners say this course on functional program design in Scala focuses on advanced techniques and topics in Scala. The lectures are clear and engaging, and the assignments are challenging but doable. Overall, this well-structured and interesting course is highly recommended for those who want to learn more about functional programming.
This course covers advanced concepts in functional programming, such as implicits and reactive programming.
"Much harder than the first course of this specialization."
"The last week is difficult, but worth it!"
"Challenging but satisfactory, mind opening."
The course instructor, Martin Odersky, is an expert in Scala and provides clear explanations.
"Martin is smart and knowledgeable."
"The "simple, yet rigorous" teaching methodology prevalent at the EPFL is once more at work."
"Martin Odersky has a beautiful, calming, sweet voice, that is able to entertain and guide the student even through the most difficult concepts."
Many assignments in this course are difficult but rewarding.
"All assignments except the last one are super difficult."
"The assignments are tough but worth it."
"I really enjoyed the type directed programming section. It gave me new perspective to look at things."
Some learners have noted that the course content can be disorganized and lacking a clear connecting thread.
"This course will shatter your desire to learn Scala."
"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."
"For the content of last 3 weeks, I struggled through some of them, I found some of them quite irrelevant."
This course assumes some prior knowledge of Scala.
"Heed the warnings that you must be an experienced Scala programmer to do well in this class."
"I took the "beginning" class, but even that was challenging and I didn't complete the later assignments."
