Option 1
React
The default; biggest ecosystem; steepest learning curve.
Best for
New projects targeting any audience, hiring at any scale, projects needing the broadest library / tooling support.
Pros
- Largest ecosystem: every library, every meta-framework, every hosting platform supports React first
- Hireability: React experience is the most-sought frontend skill on every job board
- Meta-frameworks (Next.js, Remix, Astro) all started with React-first or React-only
- React Server Components + Suspense are the most-mature server-rendering primitives in any framework
- TypeScript story is best-in-class
- Native (React Native), VR (React Three Fiber), AI (LangChain.js) all assume React
Cons
- Steeper learning curve: hooks, refs, useEffect rules, key gotchas, controlled vs uncontrolled — lots to memorize
- Re-render reasoning is harder than Vue's automatic dependency tracking
- Bundle size is bigger than Vue or Svelte for the same app
- JSX is divisive (some love, some hate)
