You Don't Know JS: this & Object Prototypes

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 €œYou 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
