react: 249k-star UI library reduces DOM manipulation burden with declarative rendering

Efficiently updates only the components that need to change when data changes, simplifying the construction of complex interfaces. The declarative view structure improves code predictability and makes debugging easier.

Each component manages its own state and operates independently. Writing logic in JavaScript instead of templates provides flexible data passing, and since state is not directly exposed to the DOM, maintainability is improved.

It can be adopted incrementally without being constrained by existing tech stacks. It supports server-side rendering based on Node.js and mobile app development via React Native, making it usable in both web and native environments.
