Problem Statement
MVC, MVP, and MVVM are three architectural patterns that solve the same fundamental problem: how to separate your user interface (UI) from your business logic and data. You encounter this dilemma every time you build a screen that displays data, handles user input, and updates the view—whether you're writing a web app, a mobile app, or a desktop tool. Without a clear structure, your code quickly turns into a tangled mess of event handlers and DOM queries that’s impossible to test, debug, or reuse. These patterns give you a proven blueprint to keep things organized, but choosing the wrong one can lead to unnecessary complexity or painful refactoring down the road.
Core Explanation
All three patterns divide an application into three distinct roles:
Model – The data and business logic (e.g., a user object, a database query, an API call).
