Answer
Route Guards protect navigation, enforce security, manage unsaved changes, restrict lazy loading, and validate data before route activation.
Quick Answer
Route Guards in large apps: CanActivate guards protect routes from unauthorized access (check auth token, roles). CanLoad prevents lazy module download for unauthorized users (saves bandwidth). Resolve pre-fetches data so the component has data on initialization (no loading states in component). CanDeactivate warns users about unsaved form data before navigating away. Guards are essential for security and UX in large apps.
