Higher-Order Functions
It is natural for a programming paradigm that centers on functions to treat them as first-class citizens. In functional programming, functions are values and can be stored in variables and passed as arguments. Functions that consume or produce other functions are said to be higher-order functions. Using higher-order functions, computations can be parameterized by other computations in powerful ways.
9.1 Functions as Values
Previous chapters have shown how pure functions from immutable values to immutable values can be used as building programming blocks, and how complex computations can be achieved by composing functions, including composing a function with itself through recursion. Although pure functions, ...
