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
