You still need to go through a port with Blazor, but you can minimize those calls for the most part. DOM manipulation was slow as recently as a few years ago, but improvements to Blink have made it blazingly fast. I agree with Svelte that we no longer need a virtual DOM https://svelte.dev/blog/virtual-dom-is-pure-overhead https://svelte.dev/blog/virtual-dom-is-pure-overhead Edit: I didn't answer your question. There's nothing wrong with JS bindings. Both Blazor and Dart use them, which could get awkward going from Blazor -> Dart (as JS) -> JavaScript lib. I'm considering TypeScript again because no port is needed to call JS libs.
