If you're like most developers, you rely heavily on JavaScript to build interactive and quick-responding web applications. The problem is that all of those lines of JavaScript code can slow down your apps. This book reveals techniques and strategies to help you eliminate performance bottlenecks during development. You'll learn how to improve execution time, downloading, interaction with the DOM, page life cycle, and more. Zakas and five other JavaScript experts—Ross Harmes, Julien Lecomte, Steven Levithan, Stoyan Stefanov, and Matt Sweeney—demonstrate optimal ways to load code onto a page, and offer programming tips to help your JavaScript run as efficiently and quickly as possible. You'll learn the best practices to build and deploy your files to a production environment, and tools that can help you find problems once your site goes live. Nicholas C.

If you agree that this is a valuable source of information, then please pay for that value by downloading a legal copy either digital or print of the book. On the other hand, if you find that this book is no more valuable than the free information on the web, then please discard your pirated copy and use those free information sources. Conventions Used in This Book I use the following typographical conventions in this book: Italic Is used for emphasis and to indicate the first use of a term.

Italic is also used for email addresses, URLs and file names. Constant width italic Is used for the names of function parameters, and generally as a placeholder to indicate an item that should be replaced with an actual value in your program. Example Code The examples in this book are available online.

In general, you may use the code in this book in your programs and documentation. For example, writing a program that uses several chunks of code from this book does not require permission.

Answering a question by citing this book and quoting example xiv Preface code does not require permission. This book will help you master the language.

If you are already familiar with other programming languages, it may help you to know that JavaScript is a high-level, dynamic, untyped interpreted programming language that is well-suited to object-oriented and functional programming styles. JavaScript derives its syntax from Java, its first-class functions from Scheme, and its prototypebased inheritance from Self.

But you do not need to know any of those languages, or be familiar with those terms, to use this book and learn JavaScript. Except for a superficial syntactic resemblance, JavaScript is completely different from the Java programming language. And JavaScript has long since outgrown its scripting-language roots to become a robust and efficient general-purpose language.

The latest version of the language see the sidebar defines new features for serious large-scale software development. For the last decade, all web browsers have implemented version 3 of the ECMAScript standard and there has really been no need to think about version numbers: the language standard was stable and browser implementations of the language were, for the most part, interoperable.

Recently, an important new version of the language has been defined as ECMAScript version 5 and, at the time of this writing, browsers are beginning to implement it.

Version 4 of ECMAScript was under development for years, but proved to be too ambitious and was never released. To be useful, every language must have a platform or standard library or API of functions for performing things like basic input and output.

The Node Beginner Book

The core JavaScript language defines a minimal API for working with text, arrays, dates, and regular expressions but does not include any input or output functionality. Part I of this book covers the language itself and its minimal built-in API. Part IV is the reference section for client-side JavaScript.


This book covers low-level fundamentals first, and then builds on those to more advanced and higher-level abstractions. The chapters are intended to be read more or less in order. But learning a new programming language is never a linear process, and describing a language is not linear either: each language feature is related to other features and this book is full of cross-references—sometimes backward and sometimes forward to material you have not yet read.

So, naturally, I came to this book. After reading it, there are perhaps four tips from the entire book that are relevant to developers today. The rest are based off micro-benchmarks of browsers like IE 6 and Firefox 4 - needless to say, how browsers handle JS has changed a lot since then, so these benchmarks are useless.

In conclusion: If you aren't concerned about shaving off a couple of ms from your code, you can find much of this advice for free, online, with up-to-date benchmarks and comparisons. Compra verificada. This book is a good reference on how to optimize JavaScript applications and also an interesting read in case you want to know how things work "under the hood".

Many of the techniques presented also works for other programming languages and are well-known performance tricks and can be used without increasing too much the code complexity, which is a huge gain, you're not just becoming a better JavaScript developer but also a better developer.

JavaScript: The Definitive Guide, 6th Edition

The book has some typo mistakes which doesn't affect the understanding and some of the line graphs used to show browsers benchmark are hard to read since all the lines look the same as of 1st Edition.

I strongly recommend this book to any intermediate to advanced developer who wants to learn how to improve the overall performance of JavaScript applications since it is a concise and accurate compilation of best practices, even if you know a lot about the subject you may learn a few new tricks or understand a little bit better why it works For anyone concerned with optimizing JavaScript performance, this is the book for you.

Nothing in here should be a surprise for an experienced and good developer and some of the techniques you already know, but it's a valuable collection to have at your fingertips. They are practical, imminently usable, and immediately applicable.

I'm the lead developer for a fashion retailer and bought this book in order to learn more about how to make the site faster, especially because we have a lot of third party scripts.

From the get-go, the author just dives in and I learned about blocking scripts and techniques on how to stack code to minimize page render time. This is a mercifully thin book, but densely packed with information and techniques. Be warned however, that this is not for JavaScript newbies.
