🧩 The ViewTransition API is a modern web API that enables smooth, declarative transitions between different views or UI states in a single-page application (SPA).

Instead of manually managing animations, developers can use startViewTransition() to automatically animate DOM changes—such as switching pages, updating content, or navigating tabs—with minimal code. It integrates seamlessly with the browser's rendering pipeline to deliver performant, native-like transitions.

Usage Example:

function handleClick(e) {
  // Fallback for browsers that don't support this API:
  if (!document.startViewTransition) {
    updateTheDOMSomehow();
    return;
  }

  // With a View Transition:
  document.startViewTransition(() => updateTheDOMSomehow());
}

✨ View transitions aren't tied to any specific framework—they work across different app architectures and even between separate documents.

How it works:

1. The browser captures snapshots of old and new states
2. DOM updates happen while rendering is paused
3. Transitions are handled with CSS Animations

⚠️ Note: This feature isn't fully supported across all browsers yet.
