Most modern frameworks can be AOT compiled in that sense - React, Vue, Riot - they load JS code only at runtime, but still use templates (VDOM, strings or another representation) as blueprints to update/manipulate the DOM. AFAIK Angular still uses dirty checking; Angular Ivy, yet to be released, will move to something a little closer (incremental-dom), but still not the same. What Svelte does is precompile the UI update code[1], changing text nodes, attributes, children, targeting DOM nodes directly. Think Prepack[2] vs DOM diffing.

AFAIK Ivy and pre-Ivy operate on similar fundamental principals, which is why Ivy is a drop-in replacement.
