Video Description

Functional programming has been around for decades, but it only overtook the JavaScript community in recent years. The impact is undeniable and yet with all the material available it still isn’t always easy to grok.

This course delivers the building blocks of the functional paradigm in a way that makes sense to JavaScript developers. Animated visualizations help explain difficult concepts such as higher-order functions, lenses and persistent data, partial application and currying and then write code so you understand concepts before trying to apply the knowledge them.

Many functional programming videos leave students feeling as if they just learned something that can’t quite be useful, but in Foundations of Functional Programming you’ll build stateless UI components and implement your own higher-order functions that integrate them with JSX and virtual-dom using no frameworks, just functional programming and modern JavaScript.

Style and Appraoch

We’ll cover new concepts and go over them, usually step by step first with visualisations and then use those concepts writing practical examples in JavaScript. You can follow along using the course materials.
