I'm lost.

React builds interactive UIs (web, mobile). After each interaction, the virtual DOM is programmatically recreated and reconciled to the actual DOM.

But reactpy is running on a backend sever??? Is each interaction resulting in a server call?

Can someone explain what is going on?

EDIT: Ah, okay, thanks. Every re-render is a network call. If people complained about web UI performance before..... :)
