MVC

ELI5 — The Vibe Check

MVC is like a restaurant: the Model is the kitchen (data and logic), the View is the plate of food (what the user sees), and the Controller is the waiter (takes orders, talks to the kitchen, brings back food). They each have one job and stay in their lane.

Real Talk

Model-View-Controller is an architectural pattern that separates an application into three components: the Model manages data and business logic, the View renders the user interface, and the Controller handles input and orchestrates the flow between Model and View.

Show Me The Code

// Controller
app.get('/users', async (req, res) => {
  const users = await User.findAll(); // Model
  res.render('users/index', { users }); // View
});

When You'll Hear This

"Rails follows MVC by default." / "Put that logic in the model, not the controller."
