Reactivity in Vue Thinking in Signals
summary
Concrete claims and concrete tools: Vue 3 (circa 2020) already exposes ref, computed, watchEffect that map to signals; Solid proves fine‑grained signals give DOM‑level updates; Vue’s reactive uses proxies and wraps nested objects, while shallowRef plus triggerRef avoids expensive proxying and forces updates. Computed values cache and re‑evaluate only when dirty; effect scopes auto‑cleanup to prevent leaks; Vue’s reactivity package and Preact/signals work standalone and can be implemented in ~20 lines of JS.
