MVC code example

Example 1: what is mvc architecture

The Model-View-Controller (MVC) is an architectural pattern that separates an 
application into three main logical components: the model, the view, and 
the controller. Each of these components are built to handle specific 
development aspects of an application. MVC is one of the most frequently used 
industry-standard web development framework to create scalable and extensible
projects.

Example 2: mvc means

MVC = Model, View, Controller architecture.
Model = SQL
View = HTML + CSS
Controller = JS

Example 4: why we used mvvm instead of mvc

Whereas the MVC format is specifically designed to create a separation of concerns between the model and view, the MVVM format with data-binding is designed specifically to allow the view and model to communicate directly with each other. This is why single page applications work very well with ViewModels.
