No matter how much experience you have with JavaScript, odds are you don’t fully understand the language. This concise yet in-depth guide takes you inside scope and closures, two core concepts you need to know to become a more efficient and effective JavaScript programmer. You’ll learn how and why they work, and how an understanding of closures can be a powerful part of your development skillset.
Like other books in the "You Don’t Know JS" series, Scope and Closures dives into trickier parts of the language that many JavaScript programmers simply avoid. Armed with this knowledge, you can achieve true JavaScript mastery.
<ul>
<li>Learn about scope, a set of rules to help JavaScript engines locate variables in your code</li>
<li>Go deeper into nested scope, a series of containers for variables and functions</li>
<li>Explore function- and block-based scope, “hoisting”, and the patterns and benefits of scope-based hiding</li>
<li>Discover how to use closures for synchronous and asynchronous tasks, including the creation of JavaScript libraries</li>
</ul>

HTML5 Cookbook: Solutions & Examples for HTML5 Developers

Schmitt, Christopher

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

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. 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 &amp; 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:
<ul>
<li>Get acquainted with JavaScript’s seven types: null, undefined, boolean, number, string, object, and symbol</li>
<li>Understand why JavaSript’s unique array, string, and number characteristics may delight or confound you</li>
<li>Learn how natives provide object wrappers around primitive values</li>
<li>Dive into the coercion controversy—and learn why this feature is useful in many cases</li>
<li>Explore various nuances in JavaScript syntax, involving statements, expressions, and other features</li>
</ul>

You Don't Know JS: 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 concise yet in-depth guide focuses on new asynchronous features and performance techniques—including Promises, generators, and Web Workers—that let you create sophisticated single-page web applications and escape callback hell in the process.
Like other books in this series, You Don’t Know JS: Async &amp; Performance 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:
<ul>
<li>Explore old and new JavaScript methods for handling asynchronous programming</li>
<li>Understand how callbacks let third parties control your program’s execution</li>
<li>Address the "inversion of control" issue with JavaScript Promises</li>
<li>Use generators to express async flow in a sequential, synchronous-looking fashion</li>
<li>Tackle program-level performance with Web Workers, SIMD, and asm.js</li>
<li>Learn valuable resources and techniques for benchmarking and tuning your expressions and statements</li>
</ul>

You Don't Know JS: Async & Performance

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 focuses on new features available in ECMAScript 6 (ES6), the latest version of the standard upon which JavaScript is built.
Like other books in this series, You Don’t Know JS: ES6 &amp; Beyond dives into trickier parts of the language that many JavaScript programmers either avoid or know nothing about. Armed with this knowledge, you can achieve true JavaScript mastery.
With this book, you will:
<ul>
<li>Learn new ES6 syntax that eases the pain points of common programming idioms</li>
<li>Organize code with iterators, generators, modules, and classes</li>
<li>Express async flow control with Promises combined with generators</li>
<li>Use collections to work more efficiently with data in structured ways</li>
<li>Leverage new API helpers, including Array, Object, Math, Number, and String</li>
<li>Extend your program’s capabilities through meta programming</li>
<li>Preview features likely coming to JS beyond ES6</li>
</ul>

You Don't Know JS: ES6 & Beyond

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 &amp; 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:
<ul>
<li>Learn the essential programming building blocks, including operators, types, variables, conditionals, loops, and functions</li>
<li>Become familiar with JavaScript's core mechanisms such as values, function closures, this, and prototypes</li>
<li>Get an overview of other books in the series—and learn why it’s important to understand all parts of JavaScript</li>
</ul>

Functional-Light JavaScript is a balanced, pragmatic exploration of Functional Programming in JavaScript.Functional Programming (FP) is an incredibly powerful paradigm for structuring code that yields more robust, verifiable, and readable programs. If you've ever tried to learn FP but struggled with terms like "monad", mathematical concepts like category theory, or symbols like (lambda), you're not alone.Functional-Light programming distills the most vital aspects of FP—function purity, value immutability, composition, and more!—down to approachable JavaScript patterns. Rather than the all-or-nothing dogmatism often encountered in FP, this book teaches you how to improve your programs line by line.
