No matter how much experience you have with JavaScript, odds areyou don’t fully understand the language. This concise, in-depth guide takes youinside JavaScript’s this structure and object prototypes. You’ll learn how theywork and why they’re integral to behavior delegation—a design pattern in whichobjects are linked, rather than cloned.
Like other books in the “You Don’t Know JS” series, this andObject Prototypes dives into trickier parts of the language that manyJavaScript programmers simply avoid. Armed with this knowledge, you can becomea 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
