Reactivity in Frontend JavaScript Frameworks
summary
Compares concrete implementations rather than definitions, building a tiny onStateChange and an autoRun to show how Vue.js style dependency tracking actually wires getters/setters to subscribers and proves it updates the DOM. Contrasts push vs pull strategies with Angular/Zone.js, React/virtual DOM and Redux, and MobX; measures tradeoffs: much less work when push tracks deps but higher memory/closure cost, mixed strategies in real frameworks, and the examples demonstrably run in the console.
