A component-based JavaScript library for building interactive user interfaces, maintained by Meta — the most widely used frontend library for anything beyond a static page.
Why I use it
Component model keeps UI code organized and reusable as an interface grows
The largest frontend ecosystem — component libraries, form tools, state management, all well-maintained
Pairs cleanly with a separate backend (Laravel, Node) via a REST or GraphQL API
Where it fits
Dashboards and admin interfaces with real interactivity
Customer-facing web apps where a static site isn't enough
