CORE DEFINITION

Divides an application into three core components: the model (data), the view (user interface), and the controller (business logic). The goal is to achieve a dynamic program design that simplifies subsequent modifications and extensions.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Separation of concerns. When making a presentation PPT, MVC also applies: the Model is your core data and conclusions, the View is the beautification and layout of the PPT, and the Controller is the logic of your presentation. Do not modify the Model (data) while working on the View (layout), as this leads to extremely low efficiency.

Anchor fast decisions

Decompose the application into three parts: the model (data), the view (interface), and the controller (business logic), enabling the program to be "dynamically" modified and extended: interface changes do not affect data, and logic changes do not require redoing the interface. The essence is separation of concerns, allowing complex systems to be divided and conquered, evolving in parallel.

MINIMUM ACTION

In progress 0/5

Practice this model in one real situation:

Define the Model: core data and state.
Define the View: the presentation layer the user sees.
Define the Controller: handles input, updates the Model, and refreshes the View.
In scenarios like presentations, make analogical transfers: Model = conclusion data, View = layout, Controller = narrative logic
do not mix changes among them.
