Prior working experience of functional javascript is needed

javascript is a multi-paradigm language, meaning that it supports programming in many different patterns. Functional programming has been around for decades, but it 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 growsss. It is the technique of building software by constructing pure functions, avoiding shared state, mutable data, and side-effects. Functional programming is analytical and the application state flows through pure functions. If you’re interested to learn the concepts required to be a functional programmer and write functional web-apps using modern javascript, then go for this Learning Path.

Packt’s Video Learning Paths are a series of individual video products put together in a logical and stepwise manner such that each video builds on the skills learned in the video before it.

The highlights of this Learning Path are:

Understand pure functions and how to refactor impure functions

Learn to handle management patterns like React and DOM events

Elevate yourself to a level of comfort writing production level functional apps

Let’s take a quick look at your learning journey…

The primary idea of this Learning Path is to help you build code to run your App in Functional javascript.

This Learning Path 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.

In this Learning Path you’ll learn techniques like combining smaller units of code into composition pipelines. You’ll learn how to reason about these composed functions and learn the laws of compositionality to deal with common issues that come along when writing compositional logic. You’ll continue building code that mirrors popular framework thinking. Students will learn how to create a state management pattern like React and how to handle DOM events (and other I/O) by encapsulating logic inside generic containers.

Finally, you’ll learn about maybe, either, future and even reactive streams with observables to write asynchronous code that looks more like synchronous FP.

After completing this Learning Path, you’ll have learned the concepts required to be a functional programmer and write functional web-apps using modern javascript.
