Most programming languages contain good and bad parts, but JavaScript has more than its share of the bad, having been developed and released in a hurry before it could be refined. This authoritative book scrapes away these bad features to reveal a subset of JavaScript that's more reliable, readable, and maintainable than the language as a whole-a subset you can use to create truly extensible and efficient code.
Considered the JavaScript expert by many people in the development community, author Douglas Crockford identifies the abundance of good ideas that make JavaScript an outstanding object-oriented programming language-ideas such as functions, loose typing, dynamic objects, and an expressive object literal notation. Unfortunately, these good ideas are mixed in with bad and downright awful ideas, like a programming model based on global variables.
When Java applets failed, JavaScript became the language of the Web by default, making its popularity almost completely independent of its qualities as a programming language. In JavaScript: The Good Parts, Crockford finally digs through the steaming pile of good intentions and blunders to give you a detailed look at all the genuinely elegant parts of JavaScript, including:
Syntax
Objects
Functions
Inheritance
Arrays
Regular expressions
Methods
Style
Beautiful features
The real beauty? As you move ahead with the subset of JavaScript that this book presents, you'll also sidestep the need to unlearn all the bad parts. Of course, if you want to find out more about the bad parts and how to use them badly, simply consult any other JavaScript book.
With JavaScript: The Good Parts, you'll discover a beautiful, elegant, lightweight and highly expressive language that lets you create effective code, whether you're managing object libraries or just trying to get Ajax to run fast. If you develop sites or applications for the Web, this book is an absolute must.

About this product: Since the earliest days of Internet scripting, Web developers have considered JavaScript: The Definitive Guide an essential resource. David Flanagan's approach, which combines tutorials and examples with easy-to-use syntax guides and object references, suits the typical programmer's requirements nicely. The brand-new fourth edition of Flanagan's "Rhino Book" includes coverage of JavaScript 1.5, JScript 5.5, ECMAScript 3, and the Document Object Model (DOM) Level 2 standard from the World Wide Web Consortium (W3C). Interestingly, the author has shifted away from specifying--as he did in earlier editions--what browsers support each bit of the language. Rather than say Netscape 3.0 supports the Image object while Internet Explorer 3.0 does not, he specifies that JavaScript 1.1 and JScript 3.0 support Image. More usefully, he specifies the contents of independent standards like ECMAScript, which encourages scripters to write applications for these standards and browser vendors to support them. As Flanagan says, JavaScript and its related subjects are very complex in their pure forms. It's impossible to keep track of the differences among half a dozen vendors' generally similar implementations. Nonetheless, a lot of examples make reference to specific browsers' capabilities.
Though he does not cover server-side APIs, Flanagan has chosen to separate coverage of core JavaScript (all the keywords, general syntax, and utility objects like Array) from coverage of client-side JavaScript (which includes objects, like History and Event, that have to do with Web browsers and users' interactions with them. This approach makes this book useful to people using JavaScript for applications other than Web pages. By the way, the other classic JavaScript text--Danny Goodman's JavaScript Bible--isn't as current as this book, but it's still a fantastic (and perhaps somewhat more novice-friendly) guide to the JavaScript language and its capabilities. --David Wall
Topics covered: The JavaScript language (version 1.0 through version 1.5) and its relatives, JScript and ECMAScript, as well as the W3C DOM standards they're often used to manipulate. Tutorial sections show how to program in JavaScript, while reference sections summarize syntax and options while providing copious code examples.
JavaScript is an essential language for creating modern, interactive websites, but its complex rules challenge even the most experienced web designers. With JavaScript: The Missing Manual, you'll quickly learn how to use JavaScript in sophisticated ways -- without pain or frustration -- even if you have little or no programming experience.
JavaScript expert David McFarland first teaches you the basics by having you build a simple program. Then you'll learn how to work with jQuery, a popular library of pre-built JavaScript components that's free and easy to use. With jQuery, you can quickly build modern, interactive web pages -- without having to script everything from scratch!
Learn how to add scripts to a web page, store and manipulate information, communicate with the browser window, respond to events like mouse clicks and form submissions, and identify and modify HTML
Get real-world examples of JavaScript in action
Learn to build pop-up navigation bars, enhance HTML tables, create an interactive photo gallery, and make web forms more usable
Create interesting user interfaces with tabbed panels, accordion panels, and pop-up dialog boxes
Learn to avoid the ten most common errors new programmers make, and how to find and fix bugs
Use JavaScript with Ajax to communicate with a server so that your web pages can receive information without having to reload
This eagerly anticipated update to the breakout book on JavaScript offers you an in-depth look at the numerous advances to the techniques and technology of the JavaScript language. You'll see why JavaScript's popularity continues to grow while you delve through topics such as debugging tools in Microsoft Visual Studio, FireBug, and Drosera; client-side data storage with cookies, DOM storage, and client-side databases; HTML 5, ECMAScript 3.1, the Selectors API; and design patterns including creational, structural, and behavorial patterns.
About this product: Once listed in the "nice to have" sections of job postings, these days the knowledge of JavaScript is a deciding factor when it comes to hiring web developers. And rightly so. Where in the past we used to have the occasional few lines of JavaScript embedded in a web page, now we have advanced libraries and extensible architectures, powering the "fat-client", AJAX-type rich internet applications.
JavaScript is the language of the browser, but it's also heavily employed in many other environments: server-side programming, desktop applications, application extensions and widgets. It's a pretty good deal: you learn one language and then code all kinds of different applications. While this book has one chapter specifically dedicated to the web browser environment including DOM, events, and AJAX tutorials, the rest is applicable to all the other environments too.
This book treats JavaScript as a serious object-oriented language, showing you how to build robust, maintainable, and powerful libraries and applications. Along the way, we cover many of the recent innovations such as AJAX, JSON, and interesting design and coding patterns. After reading this book, you'll be prepared to ace your JavaScript job interview and even impress with some bits that the interviewer maybe didn't know. You should read this book if you want to be able to take your JavaScript skills to a new level of sophistication.

Who is this book written for?
The book requires no prior knowledge of JavaScript and works from the ground up to give you a thorough grounding in this powerful language. If you do already know some JavaScript, you will find plenty of eye-openers as you discover just what the language can do.
This book takes a do-it-yourself approach when it comes to writing code, because the best way to really learn a programming language is by writing code. You are encouraged to type code into Firebug's console, see how it works and then tweak it and play around with it. There are practice questions at the end of each chapter to help review what you have learned.
So you're ready to make the leap from writing HTML and CSS web pages to creating dynamic web applications. You want to take your web skills to the next level. And you're finally ready to add "programmer" to the resume. It sounds like you're ready to learn the Web's hottest programming language: JavaScript. Head First JavaScript is your ticket to going beyond copying and pasting the code from someone else's web site, and writing your own interactive web pages.
