I was very pleased to serve as a reviewer on this book. The book is very well-written and is packed with a ton of useful information and practical techniques. The Knockout.JS sections are very clear and approachable to beginners and advanced developers alike. The book especially shines when it comes to unit testing Web apps using Jasmine and the sections on Node.JS, Gulp.JS, Karma, and Phantom.JS are equally impressive. Using the libraries and techniques described in this book have definitely improved my daily development workflows. I highly recommend this book!

The author does a great job of diving into the MVVM pattern, Knockout.js, as well as a host of technologies and frameworks that can be used to create automated tests for a single page application, including Gulp, postal.js and Jasmine. The writing is crisp and clear, and the book as a whole was a joy to read. Highly recommend.

Messora does a fantastic job of reviewing basics of the MVVM development pattern. As a seasoned JavaScript developer who’s used Knockout on a daily basis for a few years and is interested in developing highly testable Single Page Applications (SPAs), this book was of great value. Best practices are clearly identified, and a thorough explanation is provided for each. Ever wondered how to adopt separation of concerns in the JavaScript world to avoid spaghetti code and why it’s a good idea to avoid using jQuery as the cornerstone of your web application? Ever wondered when to choose BDD over TDD to satisfy your testing needs? The answers are found within.Third party libraries such as Jasmine, Gulp, Karma, Phantom, and Postal are introduced. Coming from a Mocha and Grunt background myself, it was worthwhile to see the differences in Jasmine and Gulp, respectively. If you’re just getting started with Jasmine or if you want a refresher course on writing testable JavaScript, consider this book. It’s also a good read for those coming from a jQuery background who are beginning to explore the plethora of MV* frameworks/libraries out there.
