### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Not for the faint at heart, but very important core concepts
  

*by C***L on Reviewed in the United States on March 14, 2011*

Let me just say this up front--this book contains some advanced JavaScript techniques and code, and is not for the beginning or even intermediate JavaScript programmer. Even advanced practitioners may want to go back through for a second reading to ensure that all the concepts within are fully understood, especially when and how to use these patterns, as well as the advantages and disadvantages of each in context of the JavaScript implementations. Here we have two advanced authors, one from Google (Dustin Diaz), the other from Yahoo! (Ross Harmes), who have extensive experience building large-scale JavaScript-based API systems. They present 12 design pattern implementations in JavaScript, with examples of how each could be used, as well as the important core concepts of interfaces, encapsulation, information hiding, inheritance and chaining. Even if you only come away from the book learning and implementing one of the patterns or concepts in your code, it will help make the code you write more scalable, extensible, and longer lasting.

    Valuable if you do non-trivial work with JavaScript
  

*by F***O on Reviewed in the United States on June 16, 2008*

Back in the early days Design Patterns examples mostly used C++ as language. This day Java is the typical choice, with an increasing amount of C#. Usually if you are familiar with any of those languages, porting the sample code to a different platform isn't that hard. Unfortunately JavaScript is quite a different beast, first of all is not class based, it's loosely typed, it doesn't support interfaces etc. JavaScript has a whole bunch of peculiarities that make it really hard to translate those Java/C# samples. That's why this book is really welcomed. The authors stick with mainstream, well-know patterns, nothing new, but they "translate" those patterns in JavaScript, offering working samples. I tend to disagree with them whenever they pretend to add interface-like functionality to JavaScript; yet, I think they made an excellent job, a book that can be really valuable if you do non-trivial work with JavaScript

    Great read
  

*by A***R on Reviewed in the United States on August 10, 2010*

Must warn the reader that I'm not a great JS hacker and probably only a decent engineer in general . . However, having seen (and probably written) quite a bit of hokey and shoddy code to get the job done, I'm hoping I've learned enough to distinguish the good from the bad.With that being said . . I'd highly recommend this book for all the developers looking to learn and develop a well-structured and organized approach to writing clean Javascript. The first six chapters are an excellent review of OOP principles and how to successfully implement them in Javascript. The rest of the book reads easy since the design patterns are explained well and then integrate different use-cases into each pattern's lesson. Each chapter also has a succinct summary detailing when and how to apply the covered design pattern. Overall, I really enjoyed the book and feel like it's improved my approach to Javascript and coding.
