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.

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.

Meilleurs avis pour FUNCTIONAL PROGRAM DESIGN IN SCALA
par HH23 juil. 2016
Really enjoyed doing the course. Learned a ton of Stuff. Functional programming design is amazing. It's like learning Object Oriented programming (with design patterns) for the first time.
par EM28 oct. 2016
Interesting concepts analyzed in through functional and scala toolset. I enjoyed the homework variety and I think more than few things can be applied in real applications
par CP27 juin 2016
Maybe an unfair comparison but I am comparing this with the principles of reactive programming. That had much more contents such as actors, etc. Having said that this is a good course by itself.
par NG30 juil. 2016
This was just a great continuation of a great beginning after the previous course.
I hope that in the future Martin Odersky will publish more courses.
Thank you !
