Declarative: React makes it painless to create interactive UIs.
Design simple views for each state in your application, and React
will efficiently update and render just the right components when
your data changes. Declarative views make your code more
predictable, simpler to understand, and easier to debug.

Component-Based: Build encapsulated components that manage their own
state, then compose them to make complex UIs. Since component logic
is written in JavaScript instead of templates, you can easily pass
rich data through your app and keep the state out of the DOM.

RSC combines the simple “request/response” mental model of
server-centric Multi-Page Apps with the seamless interactivity of
client-centric Single-Page Apps, giving you the best of both worlds.
