Use Knockout.js to design and build dynamic client-side web applications that are extremely responsive and easy to maintain. This example-driven book shows you how to use this lightweight JavaScript framework and its Model-View-ViewModel (MVVM) pattern. You'll learn how to build your own data bindings, extend the framework with reusable functions, and work with a server to enhance your client-side application with persistence. In the final chapter, you'll build a shopping cart to see how everything fits together. If you're a web developer with experience in JavaScript, HTML, and CSS, you're ready for Knockout.
