Functional programming is a problem-solving paradigm that differs drastically from the imperative programming style of languages like C++ or Java. While functional programming principles have invaded most modern programming languages to some degree, there is no language that embraces this paradigm quite as Haskell does. As a result, Haskell code can reach a level of expressiveness, safety, and elegance that is difficult to achieve in other programming languages.

This course will introduce you to the core concepts of functional programming in Haskell. You will learn how to write pure functions using techniques such as pattern matching and recursion, and how to work with Haskell's powerful List data type. You will understand the basics of Haskell's powerful type system and define your own data types. Finally, you’ll learn how to perform IO operations the Haskell way. By the end of this course, you’ll have a new paradigm to add under your belt and you can start using functional programming in your own projects.

# Recap

Congratulations on finishing the **Functional Programming in Haskell** course! 

With the knowledge acquired in this course, you should now be able to write fairly complex Haskell programs such as the maze solver from the previous lesson yourself.

In particular, you

- Know about the most important predefined Haskell data types, including **numbers**, **strings**, **lists**, and **tuples**.
- Have a broad toolset for writing functions, including **recursive** and **higher-order** functions.
- Understand core concepts of functional programming in Haskell such as **currying**, **laziness**, and **lambda expressions**.
- Know how to create your own data types and  add them to **type classes**.
- Can handle **input/output** operations and combine them with pure functional programs.

Let's recap what we have learned and look at some Haskell topics that lie ahead.
