In computing, a web application or web app is a client-server computer program which the client (including the user interface and client-side logic) runs in a web browser. Common web applications include webmail, online retail sales, and online auction.
Progressive Web Apps are user experiences that have the reach of the web, and are:
Reliable – Load instantly and never show the downasaur, even in uncertain network conditions.
Fast – Respond quickly to user interactions with silky smooth animations and no janky scrolling.
Engaging – Feel like a natural app on the device, with an immersive user experience.
This new level of quality allows Progressive Web Apps to earn a place on the user’s home screen.
