Curriculum

Section 1: Deep Dive into Functional JavaScript

Section 2: Implementing and Testing Applications using Functional JavaScript

Course Description

Harness the power of functional programming to build and test real-world applications

Requirements

  • This Learning Path follows a theoretical and practical approach for developing maintainable applications in mostly functional style.

Description

Functional programming is a style of writing programs by simply composing a set of functions. It helps to write a lot of small reusable functions and simply call them one after the other. With regard to JavaScript, we have following features to our advantage:

•    Speed
•    Simplicity
•    Versatility
•    Server Load

If you're looking forward to building maintainable real-world applications by writing code in the functional way? If yes, this then go for this Learning Path.    

Packt’s Video Learning Path is 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.

Let's take a quick look at your learning journey. This Learning Path begins with an introduction to functional programming wherein you will understand the principles of writing functional code along with its benefits and drawbacks. You will learn to write code that is easy to understand, test, and debug using ES6. You will then see how to use currying, partial evaluation, map, reduce, filter, recursion, and other functional programming concepts in ES6. Next, you will learn generator functions and the ES2017 sync-await construct which will help you set up communication with a server via an API during implementation of a web application. As you progress, you will learn lazy evaluation to optimize performance of your web application. Finally, you will implement a web application demonstrating the practical usage of most of the features that you've learned throughout this Learning Path.

By the end of this Learning Path, you will have a thorough understanding of functional programming in JavaScript and should be able to build and test your own applications.
