• Virtual DOM ensures efficient updates to the actual DOM, improving performance.

• Strong community support provides a wealth of resources, libraries, and tools for development.

• React's declarative approach simplifies UI development by focus

Real time data can be obtained using websockets, server-sent events, or polling.

• Use websockets to establish a two-way communication channel between client and server.

• Server-sent events allow servers to push data to clients over a single, long-lived connection.

• Polling involves making periodic requests to the server to fetch updated data.
