Terminology used in the course
Functional programming is a vast field and has an elaborate lexicon. Below are definitions for some of the more prominent functional programming ideas discussed throughout the course:
-
Turing machine: An abstract computation model with memory that manipulates the contents of the memory in accordance with a set of rules.
-
Function: A relation that associates elements of a domain, or a set, to those of a codomain, or another set.
-
Arity: The number of arguments a function accepts.
