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.

Summary


In this chapter, we focused on understanding ES6 classes. ES6 classes give formal support to the common JavaScript pattern of simulating class-like inheritance hierarchies using functions and prototypes. They are syntactic sugaring over prototype-based OO, offering a convenient declarative form for class patterns which encourage interoperability. ES6 classes offer a much nicer, cleaner, and clearer syntax for creating these objects and dealing with inheritance. ES6 classes provide support for constructors, instance and static methods, (prototype-based) inheritance, and super calls.

So far, JavaScript lacked one of the most basic features - modules. Before ES6, we wrote modules using either CommonJS or AMD. ES6 brings modules into JavaScript officially. In this chapter, we took a detailed look at how modules are used in ES6.

The next chapter focuses on another interesting addition to ES6 - proxies and promises.
