Functional Programming in JavaScript

JavaScript (and its ecosystem) is a language that’s evolving really fast. New libraries and frameworks appear at a frantic pace, offering new architectures and functionalities. In past articles, we’ve seen what TypeScript has in store for us as well as how to easily migrate from an old project to this JS Superset. Today’s article will be slightly different: this time, I’d like to show a couple of examples about how we can apply Functional Programming in JavaScript.

To that end, we’ll use Ramda-fantasy, a library of powerful abstractions offering a big set of Monads, and another library called Ramda, which will help us build functional pipelines and achieve immutability. Before we get started, though, a reminder: these aren’t the only libraries that offer these functionalities; search long enough and you can easily find perfectly valid alternatives.
