🆚 React vs. SignalR

React is a popular open-source JavaScript library for building dynamic user interfaces through reusable and stateful UI components, originally created by Facebook.

It supports JSX markup, a virtual DOM rendering system, hooks for state and lifecycle management, server-side rendering, concurrent rendering, and is often used as a base for other full-stack frameworks such as Next.js or Remix.

SignalR is a library for ASP.NET that enables real-time two-way communication between servers and clients.

It supports multiple transport methods (WebSockets, Server-Sent Events, long polling) with automatic negotiation, provides a Hub API for calling methods from server or client, handles connection lifecycle, supports groups and broadcast messaging, and scales via backplanes and Azure SignalR Service.
