Deep Dive into Functional JavaScript [Video]

By: Zsolt Nagy

Overview of this book

In this course, you will have an in-depth overview and the tools in your utility belt to write maintainable code in JavaScript. We will stick to the latest version of JavaScript in this course, ES2017. You don't have to know ES2017 to benefit from the course, as we will introduce the language constructs that we use during it. You will experience the benefits of functional programming even if your code is not purely functional. In this course, you will learn the building blocks that act as a utility belt in your arsenal, enabling you to write code that's easy to understand, extend, test, and debug. You will get hands-on practice on how to use currying, partial evaluation, map, reduce, filter, recursion, and other functional programming concepts in ES6.

Section 1
What are Higher Order Functions?
JavaScript functions are values. Therefore, functions can be passed to other functions, and they can also be return values of functions. This is how we create higher order functions, giving us a powerful way to write loops and callbacks in functional style. - Understand the definition of higher order functions - Recognize some built-in higher order functions - Experiment with practical examples using higher order functions
