what is the difference between the firebase web app and firebase hosting? As far as i can tell the web app is used for an app thats actually just a browser, and the firebase hosting is used just for websites.
Firebase for Web-Apps is a JavaScript library and Firebase Hosting is a web-hosting platform.
The JS can be loaded from just any web-server, but on Firebase Hosting it is better integrated with other the components in the Firebase ecosystem - and it can be deployed with the Firebase CLI.
