What is MVVM pattern

MVVM stands for Model-View-View Model. This pattern supports two-way data binding between view and View model.

• Model - The Model represents a set of classes that describes the business logic and data.
• View - The View is collection of CSS, JavaScript, html and Forms.
• View Model - The view model acts as an intermediary between the view and the model, and is responsible for handling the view logic.

This pattern is commonly used by the WPF, Silverlight etc.
