Concept:
Higher-order functions in Haskell
Headline
Lecture "Higher-order functions in Haskell" as part of Course:Lambdas in Koblenz
Details
Higher-order functions are functions that take functions as arguments or return functions as results. Much of the expressiveness and convenience of functional programming is a consequence of the status of functions to be first-class citizens. In this lecture, we focus on higher-order functions for list processing, e.g., the map function. We also look at important related concepts such as partial application of functions or anonymous functions.
