No matter how much experience you have with JavaScript, odds are you don&;t fully understand the language. This concise, in-depth guide takes you inside JavaScript&;s this structure and object prototypes. You&;ll learn how they work and why they&;re integral to behavior delegation&;a design pattern in which objects are linked, rather than cloned.

Like other books in the &;You Don&;t Know JS&; series, this and Object Prototypes dives into trickier 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:

Explore how the this binding points to objects based on how the function is called
Look into the nature of JS objects and why you&;d need to point to them
Learn how developers use the mixin pattern to fake classes in JS
Examine how JS&;s prototype mechanism forms links between objects
Learn how to move from class/inheritance design to behavior delegation
Understand how the OLOO (objects-linked-to-other-objects) coding style naturally implements behavior delegation
