It follows the [**Model-View-ViewModel (MVVM) pattern**](https://www.mindstick.com/forum/157860/how-does-the-mvvm-pattern-work-in-knockoutjs-and-why-is-it-important), which provides a clear separation between the UI and the logic behind it. This guide will walk you through the basics of Knockout.js and how to get started with it. #### What is Knockout.js? Knockout.js is a standalone JavaScript implementation of the MVVM pattern that allows developers to: - Create dynamic user interfaces with data-binding. - [Simplify complex](https://www.mindstick.com/forum/160190/how-is-cte-used-to-simplify-complex-sql-queries) UIs by keeping the UI and data separate. - Implement a [responsive design](https://www.mindstick.com/blog/303702/responsive-design-best-practices-examples) that automatically updates the UI when the data model changes. #### Setting Up Your Environment Before you can start using Knockout.js, you'll need to include it in your project. You can either download it or include it from a CDN. #### Including Knockout.js from a CDN You can include Knockout.js in your HTML file by adding the following script tag to the `` or at the end of the ``: ```html ``` #### Creating a Simple Application Let's create a simple application that allows you to manage a list of products. We'll cover the following steps: 1. Setting up the HTML structure. 2. Creating the ViewModel. 3. Binding the ViewModel to the View. ## Step 1: Setting Up the HTML Structure Create an HTML file with the following structure: ```html Bootstrap demo

Simple Knockout.js Example

Hello, !

``` ## Step 2: Creating the ViewModel The ViewModel in Knockout.js acts as the intermediary between the View (HTML) and the Model (data). Here's the ViewModel for our product management application: ```javascript // ViewModel definition function AppViewModel() { // Observable property 'name' initialized with the value "World" this.name = ko.observable("John Doe"); } ``` ## Step 3: Binding the ViewModel to the View To connect the ViewModel to the View, you need to call the `ko.applyBindings` function and pass an instance of the ViewModel: ```javascript // Apply Knockout.js bindings to the AppViewModel ko.applyBindings(new AppViewModel()); ``` #### Running the Application 1. Save the HTML file and open it in a web browser. 2. You should see a form to add new products and a table that displays the list of products. 3. Add, edit, and delete products using the form and buttons provided. ## Read more [**Introduction Knockout.js**](https://www.mindstick.com/articles/1637/introduction-knockout-js) [**Why Knockout js is not as popular as Angular JS?**](https://www.mindstick.com/articles/336197/why-knockout-js-is-not-popular-as-angular-js) [**Form validation and request submission in knockout js**](https://www.mindstick.com/articles/335952/form-validation-and-request-submission-in-knockout-js) [**Product Drag and Drop with Knockout**](https://www.mindstick.com/articles/335973/product-drag-and-drop-with-knockout) [**Knockout.js: Building Dynamic Web Applications**](https://training.mindstick.com/courses/203/knockout-js-javascript-mvvc-framework-upcoming12) --- Original Source: https://www.mindstick.com/blog/304434/getting-started-with-knockout-js-a-beginner-s-guide Copyright © MindStick Software Pvt.
