Knockout vs Vanilla.JS: What are the differences?

## Introduction
This Markdown document compares the key differences between Knockout and Vanilla.JS for website development.

1. **Data Binding**: Knockout provides two-way data binding out of the box, automatically updating your UI whenever your data model changes. Meanwhile, in Vanilla.JS, you need to manually update the DOM whenever your data changes, leading to more code and potential bugs.
2. **MVVM Architecture**: Knockout follows the Model-View-ViewModel (MVVM) architecture, where the viewModel acts as a mediator between the model and the view, allowing for clear separation of concerns. On the other hand, in Vanilla.JS, you have to architect and manage this separation on your own.
3. **Template Binding**: Knockout offers built-in template binding functionality that allows you to bind your JavaScript objects directly to HTML templates, simplifying the rendering process. In Vanilla.JS, you would need to handle the templating process manually using methods like createElement and innerHTML.
4. **Computed Observables**: Knockout simplifies complex UI update logic by providing computed observables that automatically update whenever their dependencies change, reducing the need for manual tracking in Vanilla.JS.
5. **Event Handling**: Knockout offers simplified event handling through declarative bindings, allowing you to define event handlers directly in the HTML markup. In Vanilla.JS, event handling typically involves selecting DOM elements and manually attaching event listeners in JavaScript code.
6. **Dependency Tracking**: Knockout tracks dependencies between observables and updates the UI accordingly when these dependencies change. In Vanilla.JS, you need to manage these dependencies manually, potentially leading to inconsistent UI states.

In Summary, Knockout simplifies data binding, follows the MVVM architecture, offers template binding, computed observables, declarative event handling, and dependency tracking compared to Vanilla.JS.
