Mastering JavaScript Object-Oriented Programming

Overview of this book

ECMAScript 6 introduces several new Object-Oriented features that drastically change the way developers structure their projects. Web developers now have some advanced OOP functionality at their disposal to build large-scale applications in JavaScript. With this book, we'll provide you with a comprehensive overview of OOP principles in JavaScript and how they can be implemented to build sophisticated web applications. Kicking off with a subtle refresher on objects, we'll show you how easy it is to define objects with the new ES6 classes. From there, we'll fly you through some essential OOP principles, forming a base for you to get hands-on with encapsulation. You'll get to work with the different methods of inheritance and we'll show you how to avoid using inheritance with Duck Typing. From there, we'll move on to some advanced patterns for object creation and you'll get a strong idea of how to use interesting patterns to present data to users and to bind data. We'll use the famous promises to work with asynchronous processes and will give you some tips on how to organize your code effectively. You'll find out how to create robust code using SOLID principles and finally, we'll show you how to clearly define the goals of your application architecture to get better, smarter, and more effective coding. This book is your one-way ticket to becoming a JavaScript Jedi who can be counted on to deliver flexible and maintainable code.

Preface

Design patterns and object creation


One of the most popular topics in Object-Oriented Programming is design patterns. They are known as reusable solutions to commonly occurring software design problems. Each pattern is identified by a name and describes a situation where components need to interact with each other to achieve a specific goal.

Note

Design patterns became popular in the mid-nineties after the publishing of the book Design Patterns: Elements of Reusable Object-Oriented Software by the so-called Gang of Four (GoF): Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides.

The patterns are described so that they can be reused regardless of the language used to implement it. However, the original patterns and the subsequent ones added in the following years were mainly described for classical Object-Oriented languages. So often, they are described in terms of classes, interfaces, and other traditional constructs. Due to lack of native support for some classical OOP constructs...
