This & Object Prototypes

this & Object Prototypes

Like other books in the You Don’t Know JS series, this & 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

KYLE SIMPSON, an open-web evangelist, is passionate about JavaScript, HTML5, real-time/peer-

to-peer communications, and web performance. He’s an author, workshop trainer, tech speaker, and

avid open source community member.

Types & Grammar

No matter how much experience you have with JavaScript, odds are you don’t fully understand the

language. As part of the You Don’t Know JS series, this compact guide explores JavaScript types in

greater depth than previous treatments by looking at type coercion problems, demonstrating why

types work, and showing you how to take advantage of these features.

Like other books in this series, You Don’t Know JS: Types & Grammar dives into trickier parts of the

language that many JavaScript programmers simply avoid or assume don’t exist (like types). Armed

with this knowledge, you can achieve true JavaScript mastery.

WITH THIS BOOK YOU WILL:

■ Get acquainted with JavaScript’s seven types: null, undefined, Boolean, number, string, object, and symbol

■ Understand why JavaScript’s unique array, string, and number characteristics may delight or confound you

■ Learn how natives provide object wrappers around primitive values

■ Dive into the coercion controversy—and learn why this feature is useful in many cases

■ Explore various nuances in JavaScript syntax, involving statements, expressions, and other features

KYLE SIMPSON is an Open Web evangelist who’s passionate about all things JavaScript. He’s an

author, workshop trainer, tech speaker, and OSS contributor/leader.

Up & Going

UP AND GOING JS

It’s easy to learn parts of JavaScript, but much harder to learn it completely—or even sufficiently —

whether you’re new to the language or have used it for years. With the “You Don’t Know JS” book

series, you’ll get a more complete understanding of JavaScript, including trickier parts of the

language that many experienced JavaScript programmers simply avoid. The series’ first book, Up &

Going , provides the necessary background for those of you with limited programming experience.

By learning the basic building blocks of programming, as well as JavaScript’s core mechanisms,

you’ll be prepared to dive into the other, more in-depth books in the series—and be well on your way

toward true JavaScript.

With this book you will:

■ Learn the essential programming building blocks, including operators, types, variables, conditionals, loops, and functions

■ Become familiar with JavaScript’s core mechanisms, such as values, function closures, this , and prototypes

■ Get an overview of other books in the series—and learn why it’s important to understand all parts of JavaScript

Kyle Simpson is an Open Web Evangelist from Austin, TX, who’s passionate about all things

JavaScript. He’s an author, workshop trainer, tech speaker, and OSS contributor/leader.
