| Reactivity Model | State triggers re-renders via virtual DOM diffing. Concurrent rendering prioritizes updates. | Proxy-based fine-grained reactivity with automatic dependency tracking. No virtual DOM overhead for updates. |
| Template Syntax | JSX blends JavaScript and HTML-like syntax. Logic and markup live together in JavaScript. | HTML-based templates with directives (v-if, v-for). Feels closer to traditional web development. |
| Component Model | Functions as components with hooks for state and effects. Props flow down, events flow up. | Single-file components with template, script, and style sections. Props down, emits up. |
| Ecosystem Size | Largest frontend ecosystem. Hundreds of state managers, UI libraries, and tools to choose from. | Smaller but cohesive ecosystem. Official router and state manager (Pinia) reduce decision fatigue. |
| TypeScript Support | Excellent TypeScript support. Most React projects use TypeScript by default in 2026. | Strong TypeScript support via Composition API and defineComponent. Script setup simplifies typed components. |
| Server-Side Rendering | Next.js provides best-in-class SSR with Server Components, streaming, and edge rendering. | Nuxt provides SSR, SSG, and hybrid rendering. Nitro server engine enables deployment anywhere. |
| Mobile Development | React Native is the leading cross-platform mobile framework with a massive ecosystem. | No official mobile framework. Community options like Capacitor or NativeScript exist but are less mature. |
| Learning Curve | Moderate. JSX, hooks, and the mental model of re-renders require adjustment for newcomers. | Low. Template syntax is familiar, reactivity is intuitive, and official guides are excellent. |
