React
React is Meta's open-source library for building user interfaces with a component-based architecture. It pioneered the virtual DOM approach and has evolved to include hooks, concurrent rendering, Server Components, and streaming SSR. React's minimal core and rich ecosystem give developers the freedom to choose the best tool for each concern.
