Future of Vue
summary
Vue 3 swaps Object.defineProperty for proxies so reactivity no longer needs per-property wiring, enabling double the initialization speed and half the memory footprint in their 3,000-component benchmark; the compiler now does element-type detection, static hoisting and block-based diffing, slots become functions, and event handlers are hoisted for fewer binds. The runtime shrinks to ~10 KB gzip with tree-shakeable features, source is in TypeScript, there is a Composition API (setup/reactive/computed) for reusable logic, custom renderers are simple, and a modern/legacy build path preserves IE support.
