![Computer Networking Bible: [3 in 1] The Complete Crash Course to Effectively Design, Implement and Manage Networks. Including Sections on Security, Performance and Scalability](https://m.media-amazon.com/images/I/41H4YJnxKgL._AC_SR100,100_QL65_.jpg)
Although it's been around for almost 20 years, JS doesn't have a well established standard - the gap between different hosting environments and other important issues are not covered by ECMAScript specification.
JS is a very powerful and dynamic language to begin with, which without correct guidance may lead you to
fundamental mistakes, struggling with unanticipated, untraceable bugs and inefficient computing.
I find this book to be the 'missing guide' on how to bridge over these gaps and level up your knowledge of JS.
This book covers 68 principles of JavaScript programming in an intelligent, concise and clear manner.
It focuses mainly on pitfalls and best practices to avoid them by writing better, robust code.
68 items may sound a bit cumbersome, but the explanations are very clear and the reading direction is forward - rarely, if at all, do you need to hop back and forth between items to understand what you're currently reading.
The items span several topics:
* general JavaScript idioms - this is not a beginner's introduction, but more of a review over the language strengths and weaknesses
* variable scopes - best practices regarding global objects and other scope concerns
* functions - the identity of functions as traditional functions, methods and closures. how to use them properly in terms of context ('this' object)
* objects/prototypes - the identity of objects as classes/interfaces - proper prototyping and inheritance
* arrays - how to leverage standard Array API and common pitfalls
* API design - tips on how to write a concise and unambiguous API (be it for public use or your own code base)
* concurrency - guidelines for writing asynchronous functions properly and a brief description of Promises.

Soon to be a Classic, Just Like its Namesake
This is clearly an extraordinary book, worthy of its namesake, "Effective Java" by Joshua Bloch, which has attained the status of being "a classic", since its publication in 2001. This book, "Effective Javascript", is sure to attain the same status. It's easy to tell when a subject is being explained to you by someone who understands a subject at its core and is in touch with its essence. With so many books on Javascript (and I've read a lot of them), you come away with the impression that they were written for the sake of being able to say, "I wrote a book", not really giving you better insight into the subject matter. But, those authors apparently felt they could study up on the material and phrase things better than others. Consequently, you come out knowing pretty much what you knew going in, but with just a slightly different slant on the topics. This book, however, is a complete shift in that pattern. You'll come away possessing a greater intimacy with Javascript. Update 7/19/2015: I'm taking away one star, not because of the anything that reflects on the author, or the quality of the content presented, but because the publisher is an inattentive dullard when it comes to making sure the formatting of the Kindle edition is right. Things like (10 + 20) + 30 come out looking like (10 2+0) 3+0. See attached screenshot. It ruins an otherwise great book. My advice to David Herman is, next time you write a book, don't choose Addison-Wesley Professional because they do no honor to an otherwise excellent book.
