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.

This is a repository with an implementation of Conway's Game of Life. The game itself is implemented using several stacks in C#, F# and TypeScript. The purpose behind it is to have a small real-world example to show functional principles and features. Moreover, the repository is organized as 3 different projects an a small book/course in markdown to describe functional programming and reactive programming.
