PWAs are web applications that can be installed on a mobile device, just like a native app. They can be accessed offline, and they can use features like push notifications and location tracking.

PWAs offer a number of benefits over traditional web applications, including improved performance, reduced development costs, and increased user engagement.

PWAs are built using a combination of HTML, CSS, and JavaScript.

PWAs are built using web technologies, while native apps are built using platform-specific technologies. This means that PWAs can be accessed on any device with a web browser, while native apps can only be accessed on the platform for which they were built.

Twitter, Facebook, and Instagram are all examples of popular PWAs.

PWAs are likely to become more popular as more people use mobile devices. This is because PWAs offer a number of benefits over traditional web applications, including improved performance, reduced development costs, and increased user engagement.

PWAs are characterized by their responsive design, offline access, and support for push notifications.
