Create more robust applications with a test-first approach to JavaScript
Reliable JavaScript, How to Code Safely in the World's Most Dangerous Language demonstrates how to create test-driven development for large-scale JavaScript applications that will stand the test of time and stay accurate through long-term use and maintenance. Taking a test-first approach to software architecture, this book walks you through several patterns and practices and explains what they are supposed to do by having you write unit tests. Write the code to pass the unit tests, so you not only develop your technique for structuring large-scale applications, but you also learn how to test your work. You'll come away with hands-on practice that results in code that is correct from the start, and has the test coverage to ensure that it stays correct during subsequent maintenance. All code is provided both in the text and on the web, so you can immediately get started designing more complete, robust applications.
JavaScript has graduated from field-validation scripts to full-scale applications, but many developers still approach their work as if they were writing simple scripts. If you're one of those developers, this book is the solution you need to whip your code into shape and create JavaScript applications that work.
- Write more concise and elegant code by thinking in JavaScript
- Test the implementation and use of common design patterns
- Master the use of advanced JavaScript features
- Ensure your code's conformance to your organization's standards
If you're ready to step up your code and develop more complete software solutions, Reliable JavaScript is your essential resource.

From the Back Cover
Test first, then code, for more robust large-scale JavaScript applications
Experienced developers still struggle with the failure of large-scale JavaScript applications that collapse under their own weight. Reliable JavaScript provides the solution in the form of a test-driven workflow that produces robust applications that stand the test of time. This book uses unit tests to explain, demonstrate, and employ a wide variety of JavaScript patterns and architectures. As you follow along, you will become an expert in the test-driven development of JavaScript that is suitable for commercial software. If you are ready to bring a high level of software engineering to your JavaScript development, this book is for you.
Reliable JavaScript:
- Shows you how to write code that's verified correct the first time, and has the test coverage to remain correct throughout subsequent maintenance
- Surveys the current landscape of JavaScript frameworks for testing, dependency injection, and aspect-oriented programming
- Explains testability characteristics and how to construct objects to be testable
- Demonstrates the implementation and use of common design patterns and advanced JavaScript features and architectures
- Covers DOM access testing, including excessive updates, excessive access in loops, and XHR/JSONP requests
- Provides all of the book's code both in the text and on the companion website

A practical and insightful guide to writing better JavaScript By Joey Havelick Having consumed the standard fare of Javascript: The Good Parts and a few other of the “classics", I've always felt there was a need for a well written Best Practices book. Reliable JavaScript does a great job of fulfilling that. Building modifiable and extensible code is hard. I think this book offers a few things that will help you avoid technical debt and crippling complexity (something I've found my JS code to suffer from more easily than other languages).- Part I incorporates several base principles (TDD, SOLID) to offer a holistic view on how to build reliable JavaScript. They take an interesting approach by walking through the construction of modules using TDD to discuss why it's useful, how it works and how to avoid pitfalls.- Part II is dedicated to the discussion of proper implementation of select patterns in JS. For each pattern, I was happy to see a section on how to unit test (with many of the introductions written as “Understanding the Pattern Through Unit Tests”), representing the commitment this book takes to TDD.- Part III was of particular interest to me, someone who was a believed in SOLID principles but had a tough time applying them in JavaScript due to lack of interfaces (aka contracts). I was delighted to see a simple idea for how to get the benefits of code contract style development through testing. I'm actually considering applying this technique to some Python code, to boot. Additionally, they provide a mixin pattern which has a bit more intelligence to avoid clobbering existing properties.- Part IV and V cover miscellaneous topics and then a well written summary that will be useful when I go back to this book to remind myself what the book said about x, without needing to re-read entire chapters.I recommend this book if you've already read something like JavaScript: The Good Parts but are hoping to learn more about robust code through patterns, best practices and TDD. It’s not a TDD book per se, but its use throughout the book makes for some useful demonstrations. I don't see the material as too opinionated, as it applies to JS in general, not just a single framework, and you can pick and choose what to implement. It can get pretty deep at certain points, but the organization of the book makes it easy to jump around based on your familiarity and interest in each topic.Overall, a practical and insightful guide to writing better JavaScript.
6 of 6 people found the following review helpful. A Book to Focus Your Thoughts about How to Use Javascript By Just a buyer Very well written. I put it among the top 10% of the books in my javascript library. It is not the first javascript book to read, however, if you are coming to the javascript from some another programming language.L. Spencer isn't shy about "do's and don'ts", which is very helpful in forming your own programming style.
