11. What is the PWA?
Progressive Web Apps are experiences that combine the
best of the web and the best of apps.
They are useful to users from the very first visit in a browser
tab, no install required.

over time, it becomes more and more powerful.
It loads quickly, even on flaky networks, sends relevant push
notifications, has an icon on the home screen and loads as
a top-level, full screen experience.
