Yes, and that's the main reason why I like it. You can do advanced UIs and animations that would otherwise be very annoying in other frameworks like React Native. Plus, a canvas makes it easy to port to other platforms like desktop and web because all you need is the ability to draw pixels on a screen.
hah. I remember having to build HTML-only fallback versions of fancy Flash UI sites back in... 2002 to around 2008. We marketed this as an add-on for improved SEO. Allegedly Google used to manually check if the content matched what was in the Flash version and knock you down if it wasn't. That was probably just a rumor.
But it's more fun to rebuild the DOM inside a canvas. Then you can run it in another DOM inside a canvas inside a DOM, and stream the whole thing from a server into a thin client and call it a native app.
