MVVM

ELI5 — The Vibe Check

MVVM is MVC's cooler cousin for UI-heavy apps. The ViewModel is a translator that sits between your data and your screen — it transforms raw data into something the UI can show, and pushes UI events back to the data. Vue and Angular love this pattern.

Real Talk

Model-View-ViewModel separates UI logic from business logic using data binding. The ViewModel exposes data streams and commands that the View binds to declaratively, eliminating the need for the View to know about the Model directly. Common in Angular, Vue, and WPF applications.

Show Me The Code

// Vue MVVM - ViewModel
const useUserViewModel = () => {
  const user = ref(null);
  const displayName = computed(() => `${user.value?.firstName} ${user.value?.lastName}`);
  return { user, displayName };
};
