It has no concept of classes, and you don’t even need to define any objects in order to write code. But don’t be fooled—JavaScript is an incredibly powerful and expressive object-oriented language that puts many design decisions right into your hands. In The Principles of Object-Oriented JavaScript, Nicholas C.
Zakas thoroughly explores JavaScript’s object-oriented nature, revealing the language’s unique implementation of inheritance and other key characteristics. You’ll learn:.
Object-Oriented Programming with JavaScript 4.3 (61 ratings) Course Ratings are calculated from individual students’ ratings and a variety of other signals, like age of rating and reliability, to ensure that they reflect course quality fairly and accurately. In this section we return to objects and learn them even more in-depth.
The difference between primitive and reference values. What makes JavaScript functions so unique. The various ways to create objects. How to define your own constructors. How to work with and understand prototypes. Inheritance patterns for types and objects The Principles of Object-Oriented JavaScript will leave even experienced developers with a deeper understanding of JavaScript. Unlock the secrets behind how objects work in JavaScript so you can write clearer, more flexible, and more efficient code.

With the best practices and optimization techniques you'll learn in this book, you can optimize performance without sacrificing a rich user interface.
Using a combination of innovative ideas and intelligent use of HTML, CSS, JavaScript, and plug–ins, this book shows you how to make decisions based on best web standard development practices and real–world browser data. Through practical examples, you'll see how to optimize both design and performance with an eye toward future enhancements and efficient maintenance.
Starting with the essential principles and techniques of semantic markup, build efficient, responsive web applications based on web standard best practices and real–world experience. Apply practical techniques and see how to reuse examples of broadly relevant page components to improve the interface and performance of existing sites.
Explore ways to push the boundaries of the possible with existing browser technology. Author by: Martin Rinehart Language: en Publisher by: Apress Format Available: PDF, ePub, Mobi Total Read: 60 Total Download: 379 File Size: 55,8 Mb Description: This brief book explains the advantages of the object model, inheritance, both classical and prototypical, and shows how these concepts can be implemented in JavaScript. It also shows how object programming (OP) opens a new world of design possibilities that go far beyond inheritance. This book will help the intermediate JavaScript programmer learn to use both types of inheritance. For classical inheritance, it is accompanied by a substantial online system (a windowing UI library) that shows classical inheritance at its best. The same system shows how OP 'capabilities' can eliminate much of the need for inheritance.
For experienced JavaScript programmers, this book shows why most of the old views of JavaScript's inheritance have not done it justice. JavaScript classes inherit from JavaScript's prototypes, a fact that makes JavaScript's prototypes, when used correctly, functional equivalents to C classes (not to prototypes in true prototypical languages, like Self). JavaScript's object programming (not inheritance) is what separates it from classical OOP languages like C and Java. Most important, basing inheritance on JavaScript's prototypal chain is possible, but is not the best choice for prototypal inheritance or classical inheritance. What You'll Learn What are objects, JavaScript objects and object programming What is and how to use inheritance and JavaScript inheritance as well as inheritance alternatives How to design for JavaScript What are and how to use OO principles in JavaScript How to use Constructors with JavaScript and more AudienceThis book is for both intermediate and advanced JavaScript and Web development programmers. However, any programmer will understand the concepts and any JavaScript programmer should understand all of the concepts in this book. The code there is shows examples of the concepts discussed.

The book then details how to implement and take advantage of several design patterns in JavaScript. Each chapter is packed with real-world examples of how the design patterns are best used and expert advice on writing better code, as well as what to watch out for. Along the way you’ll discover how to create your own libraries and APIs for even more efficient coding.

Object-Oriented Programming is a popular style of programming that has taken root in JavaScript since the beginning. It's so deeply rooted in JavaScript that many of JavaScript's native functions and methods are written in the Object Oriented style; you'll also find many popular libraries written in the Object Oriented style as well. If you already have prior experience with Object Oriented Programming in another language, please put aside the knowledge you know, and read through the entire module with a beginner's mind. Table of Contents.
This is because Object Oriented Programming in JavaScript is very different from Object-Oriented Programming in other languages. If you hold on to your current ideas, you might make Object Oriented Programming in JavaScript exponentially more difficult than it is. Now, let's begin by finding out what Object Oriented Programming is about.
Object-Oriented Programming is about two things:. Creating individual objects from a common object. Inheritance For this article, we'll only cover the first part. We'll look at inheritance in another article.
