Functional Programming in JavaScript

Envato Tuts+ Courses

Course Description

Learn the basics of functional programming in JavaScript. You’ll take a small, mostly imperative website and refactor it using practical declarative and functional concepts. You’ll learn about pure functions, side-effects and declarative style while building a small functional utility library. The project will demonstrate how Underscore or Lodash functions like filter, map, and reduce really work. Focused on practical understanding over philosophy, this is a great basic intro to functional programming that will prepare you for deeper exploration.

What You’ll Learn

• How the functional style of programming works in JavaScript.
• What declarative style is, and how to make your filter declarative.
• Working with higher-order functions and pure functions.
• How to build your own utility library, and how to use popular libraries like Underscore and Lodash.
• Put it all into practice by building a project: a simple filtering function for a website displaying a list of beers.
