In the previous chapter, you learned about functions in Haskell. Many times, in real-world applications you’ll work with functions that recall themselves, which is a process called

. In this chapter, you will learn what recursion is, see some concrete examples, and learn how you implement them in Haskell and how to apply recursion on lists.
Recursion in computer science is a method of solving a problem where the solution depends on solutions to smaller instances of the same problem (as opposed ...
