As I understand it - please correct me if I'm wrong! > HTML itself is definitely declarative HTML is the markup (not programming) language (which is Javascript). The API to actually change the DOM is imperative. See https://developer.mozilla.org/en-US/docs/Web/API/Node https://developer.mozilla.org/en-US/docs/Web/API/Node (I don't quite grasp why they felt the need to specify that) > Why are DOM-diffs something that is done by userland libraries? I guess if the browser provided primitives to build trees and diff them that would be cool. But I presume using WASM *is getting the native-browser code to do the diffing.
