No matter how much experience you have with JavaScript, you don't fully understand the language. This concise, detailed guide takes you to this structure of JavaScript and object prototypes. You will learn how they work and that they are an integral part of behavior delegation, a design pattern where objects are linked together rather than cloned.

Like the other books in the "You Don't Know JS" series, this book and Object Prototypes dive into the more difficult parts of the language that many JavaScript programmers simply avoid. Armed with this knowledge, you can become a true JavaScript master.

With this book you will:

Discover how this binding points to objects based on how the function is called

Look at the nature of JS objects and why you need to point to them

Learn how developers use the mixin pattern to emulate classes in JS

Examine how JS's prototype mechanism creates links between objects

Learn how to move from class/inheritance design to behavior delegation

Understand how the OLOO (objects bound to other objects) coding style natively enforces behavior authorization
