Vue 3.0 Updates
summary
Ground-up rewrite of the Virtual DOM and a new compiler deliver about 100% speed increase and roughly half the memory use (example: 3,000 stateful components drop from ~280ms to ~126ms). Reactivity moves from getters/setters to proxies for full mutation detection (adds property add/delete, array indices, Map/Set, classes). Runtime targets tree-shaking and yields a tiny ~10 KB gzipped runtime, plus a createRenderer API under 200 lines for custom native or canvas renderers. New observable API, render-tracking hooks and experimental time-slicing demos are included.
