Progressive Web Apps (PWAs) are web applications that use modern web technologies to deliver a user experience similar to native mobile apps. They can be accessed through a web browser and offer features like offline access, push notifications, and fast loading times. PWAs are designed to work on any device, providing a seamless experience across different platforms. One of the key benefits of PWAs is their ability to be installed on a user's device without going through an app store. This makes them easier to distribute and update. Additionally, PWAs are built to be responsive, ensuring they look and function well on various screen sizes.
