Learning Path: JavaScript: Reactive & Functional JavaScript

Description

Although JavaScript has many diverse applications, it has become ‘the programming language for the Web’ in the recent times. Almost always, when you see something working smoothly and interactively on the Web, you can assume that there is some JavaScript code running in the background.

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.

JavaScript: Reactive and Functional JavaScript begins with describing what JavaScript is and how browsers use it. We get started with the essentials—the JavaScript syntax. This includes comments, operators, variables, conditionals, loops, and functions. With the basics in place, we move on to learn about reactive programming, understand its need, and also look at building simple apps with good understanding of Rx. We will start off with Bacon.js and then move on to using Rx.js for both client-side and server-side applications. The final part of this Learning Path will look at writing maintainable code. You will experience the benefits of functional programming even if your code is not purely functional. You will also learn how to write code that's easy to understand, extend, test, and debug. Hands-on practice on how to use currying, partial evaluation, map, reduce, filter, recursion, and other functional programming concepts in ES6 is also covered.

By the end of this course, you will be able to optimize your JavaScript code.
