Can you build Progressive Web Apps (PWAs)?

Absolutely! Progressive Web Apps combine website and mobile app benefits. PWA features include: offline functionality (works without internet), installable (adds to phone home screen like native app), push notifications (engage users even when app closed), fast loading (instant load times), app-like interface (full-screen, smooth animations), background sync (syncs data when connection restored), and responsive design (works on all devices). PWAs are particularly effective for: e-commerce (offline browsing, faster checkout), news sites (read articles offline), social platforms (post when offline, sync later), booking systems (work anywhere), and content platforms (offline video viewing). Benefits over native apps: no app store approval needed, updates deploy instantly, single codebase for all platforms, lower development cost, and discoverable via search engines. PWAs feel native but deploy as websites. They're perfect for businesses wanting app-like experiences without iOS/Android development costs. Modern browsers fully support PWA features; older browsers fall back to standard website functionality.
