Overview of this book

Create powerful data-driven web applications using Knockout.JS, with the help of real-world examples About This Video • Use the Model-View-ViewModel software design pattern to build amazing web applications and powerful user interfaces • Configure your application to track the changes in the UI and update data automatically • Enhance the functionality of your app and make it more interactive by extending the components of your code In Detail Among the various JavaScript libraries available to developers, Knockout.JS really stands out due to the diverse features it provides and also because it promotes the use of the Model-View-ViewModel (MVVM) design pattern to build data-driven web applications. Construct power-packed apps without compromising on its flexibility and build rich user interfaces, which will update in real-time when the data model state changes, eliminating the need to refresh pages. Learning Knockout.JS will walk you through all of the key features of Knockout.JS and make it easy for you to quickly and easily build feature-and data-rich web applications that are easy to extend and maintain. We start off with a brief introduction to Knockout.JS, and its various benefits, and explore the different design patterns in context of Knockout.JS to make your JavaScript code cleaner and more manageable. After that, we will walk through and understand the relationship between Models, Views, and ViewModels, as well as creating them. Along with that, you will also learn how we can use the different data binding attributes to manipulate the output. We will also discuss and implement various important concepts such as two way data binding and dependency tracking to update your UI in real-time and to separate the components of your application into logical parts. We will analyze Knockout’s template feature to help you deal with data context in most scenarios. Then, we will take a look at how to track the changes in dependencies and subscribe to them using computed observables and subscriptions. Furthermore, you will also learn how to customize bindings and functions as well as using extenders to create our own set of Knockout tools. Finally, we will take a look at some advanced features of Knockout.JS to take your knowledge to the next level! Learning Knockout.JS is more than just an introduction; it’s a complete course on one of JavaScript’s innovative libraries.

Using Components and Custom Elements
Components and custom elements allow you to consolidate often-used code into a single, reusable unit. - Add a new View and a View Model to your project - Create a component to display a list of colors and a function to interact with the list - Implement the component in the View
