Opis

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.

Recenzje

"It promises to briefly explains the advantages of Object model and to show how these concept can be implemented in JavaScript. And it does it! ... the book starts with creating objects and explaining the two distinct models of JS objects. Then it goes into manipulation of objects, inheritance theory and practice, oop principles, etc. Pretty interesting, if you are a JS professional. There is enough code amongst the examples and each chapter finishes with a small summary." (Vitosh Academy, vitoshacademy.com, June, 2016)

O autorze

Martin Rinehart, a self-confessed JavaScript lover, set aside work on his five-volume frontend-engineering textbook project for long enough to write this small book on JavaScript inheritance. He wanted to eliminate some of the massive confusion surrounding this important subject.  Martin is the author of over a dozen books on programming, and of the JSWindows system that brings a windowing UI to browser-based applications.

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 elminate 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 prototypal languages, like Self). 

In this book, you'll learn the following:

• What are objects, JavaScript objects and object programming
  
• What is and how to use inheritance and JavaScript inheritance as well as inheritance alternativesHow to design for JavaScript
  
• What are and how to use OO principles in JavaScript
