## At a glance

- **Maintainer**: Meta
- **First release**: 2013
- **Language**: JavaScript / TypeScript
- **License**: MIT

## Learning curve

Moderate, jSX and hooks click within a few weeks, but most of the real learning is the surrounding ecosystem (routing, state management, build tooling).

## Performance

Excellent for most UIs thanks to the virtual DOM and concurrent rendering; very large lists and animation-heavy views need memoization discipline.

## Ecosystem

The largest frontend ecosystem in existence. Mature libraries for nearly everything and the deepest hiring pool in the industry.

## Ideal for

- Single-page applications and dashboards
- SaaS products that will grow for years
- E-commerce and content frontends (with Next.js)
- Teams that want the largest hiring pool

## Pros

- Massive ecosystem and the largest frontend talent pool
- Battle-tested component model used by the biggest apps on the web
- Skills and code transfer to mobile via React Native
- Backed by Meta with a huge open-source community
- Flexible, a library, not a framework, so it adapts to any architecture

## Cons

- Unopinionated, every project re-decides routing, state and data fetching
- Needs Next.js or similar for SEO and server rendering
- Hooks have re-render pitfalls that bite less experienced teams
- Ecosystem churn. State-management fashion changes every few years
