How does Angular's Zone.js change detection differ from Vue and Svelte reactivity?
Tests granular reactivity architecture. Angular Zone.js monkey-patches async to scan the full component tree; Vue uses runtime Proxy tracking; Svelte compiles runes into targeted DOM bindings.
Tests whether you understand why Angular legacy detection is coarse-grained versus Vue and Svelte fine-grained models. Strong answers contrast Zone.js monkey-patching async to trigger tree-wide dirty checking against Vue runtime Proxy tracking and Svelte compiler runes binding state to DOM nodes. It also covers performance overhead: Zone.js pays monkey-patch and digest costs for unrelated changes, while Vue and Svelte avoid work via exact dependencies. Red flag: saying Angular was always fine-grained or ignoring the zoneless Signals transition.
