React
React is the most widely used UI library, rendering interfaces from composable components with a declarative state model. Its ecosystem defines much of modern frontend development.
Pros
- Largest ecosystem. More libraries, jobs, and answers than any UI framework. 0
- Component model. Composable functions with hooks keep UI logic reusable. 0
- Cross-platform reach. React Native shares skills and code with mobile. 0
- Backed by Meta. Long-term investment and production testing at extreme scale. 0
Cons
- Just the view layer. Routing, data fetching, and state need third-party choices. 0
- Hook complexity. useEffect dependencies and stale closures trip up experienced developers. 0
- Churning best practices. Server components upended established patterns yet again. 0
- Runtime weight. Virtual DOM reconciliation costs more than compiled frameworks. 0
