Change detection in JS frameworks
summary
Survey of implementations compares Backbone 1.4’s manual model.set and event listeners that force full re-renders to AngularJS’s watcher/digest loop with a TTL of 10 and heavy re-evaluation, Angular 2+’s top‑down change detector driven by monkey‑patching zones, React 16.9’s virtual DOM reconciliation plus Redux single‑store and immutability, Vue 2’s getters/setters with Promise‑based microtask queues, and Svelte 3’s compiler‑generated DOM updates that emit imperative update code instead of diffing.
