Functional programming

In computer science, functional programming is a programming paradigm where programs are constructed by applying and composing functions. It is a declarative programming paradigm in which function definitions are trees of expressions that map values to other values, rather than a sequence of imperative statements which update the running state of the program.

https://github.com/a7mdfre7at/masterly.nonemptylist

A simple and lightweight implementation of a non-empty list in C#, inspired by Scala's List, that ensures a collection always has at least one item. This helps in reducing null-related bugs and ensures safe operations on collections with at least one element.
