PWA
PWA (Progressive Web Application) is a modern approach to creating websites that work more like regular mobile apps. Think of it as a website that can work offline, send notifications, and feel like a natural app on your phone, but without requiring users to visit an app store. This approach is becoming increasingly popular because it helps businesses reach more users while spending less on development compared to creating separate mobile apps. Companies like Twitter, Starbucks, and Pinterest use PWAs to give their users a better experience.
