Hip Hip Hooray for PWA!

According to the website Web.Dev:

"Progressive Web Apps are web applications that have been designed so they are capable, reliable, and installable."

This means the user experience resembles the same ease of interaction that occurs with a native application.

What are the three pillars?

Capable: A PWA features advanced functionality that users would wish to have.
Reliable: This is straightforward - a PWA is fast to respond and highly dependable.
Installable: A PWA runs on a variety of devices and platforms.
