              teams, and organizations.

              React components receive data and return what should appear on the

              React is a library. It lets you put components together, but it
              doesn’t prescribe how to do routing and data fetching. To build an
              entire app with React, we recommend a full-stack React framework
              like <Link href="https://nextjs.org">Next.js</Link> or{' '}

              React is also an architecture. Frameworks that implement it let
              you fetch data in asynchronous components that run on the server
              or even during the build. Read data from a file or a database, and
              pass it down to your interactive components.

                        People expect web app pages to load fast. On the server,
                        React lets you start streaming HTML while you’re still
                        fetching data, progressively filling in the remaining
                        content before any JavaScript code loads. On the client,
                        React can use standard web APIs to keep your UI
                        responsive even in the middle of rendering.

                  beginners and experts, researchers and artists, teachers and
                  students. Our backgrounds may be very different, but React
                  lets us all create user interfaces together.
