Functions

Functions Since functional programming (FP) is the focus, let’s explore essential functions. We’ll be dealing with pure functions, first-class functions, and anonymous functions. These concepts are closely related to the stack that stores function control contexts. Pure functions All functions in FP are pure functions. Therefore, every function discussed below is pure. The main benefits of FP, such as concurrency and predictability, stem from these pure functions. A fully deterministic program is realistically impossible because I/O is indeterministic....
