Overview of this book

JavaScript is an object-oriented programming language that is used for website development. Web pages developed today currently follow a paradigm that has three clearly distinguishable parts: content (HTML), presentation (CSS), and behavior (JavaScript). JavaScript is one important pillar in this paradigm, and is responsible for the running of the web pages. This book will take your JavaScript skills to a new level of sophistication and get you prepared for your journey through professional web development. Updated for ES6, this book covers everything you will need to unleash the power of object-oriented programming in JavaScript while building professional web applications. The book begins with the basics of object-oriented programming in JavaScript and then gradually progresses to cover functions, objects, and prototypes, and how these concepts can be used to make your programs cleaner, more maintainable, faster, and compatible with other programs/libraries. By the end of the book, you will have learned how to incorporate object-oriented programming in your web development workflow to build professional JavaScript applications.

Chapter 8. Classes and Modules

In this chapter, we will explore some of the most interesting features introduced in ES6. JavaScript is a prototype-based language and supports prototypical inheritance. In the previous chapter, we discussed the prototype property of an object and how prototypical inheritance works in JavaScript. ES6 brings in classes. If you are coming from traditional object-oriented languages such as Java, you will immediately relate to the well-known concepts of classes. However, they are not the same in JavaScript. Classes in JavaScript are a syntactic sugar over the prototypical inheritance we discussed in the last chapter.

In this chapter, we will take a detailed look at ES6 classes and modules - these are welcome changes to this edition of JavaScript and make Object Oriented Programming (OOP) and inheritance significantly easier.

If you are coming from a traditional object-oriented language, prototypical inheritance may feel a bit out of place for you. ES6 classes offer...
