>All frameworks that I know for WebApps, don't rely on OO though

Sure, though they rely on a lot of things that are only bundled with a web browser like the DOM and CSS and their concepts of namespacing, encapsulation features, etc.

Which concepts specifically?

Rust can provide encapsulation namespacing as well

Yes. Just saying there's less existing UI specific examples and material to draw from.
