A JavaScript runtime for server-side code — lets one language span both the frontend and backend of a project, which simplifies hiring and code-sharing.
Why I use it
One language (JavaScript/TypeScript) across the entire stack reduces context-switching and duplicate logic
Non-blocking I/O model suits real-time features — chat, live updates, webhooks
The npm ecosystem covers nearly any integration a project needs
Where it fits
Real-time features (live dashboards, chat, notifications)
Lightweight APIs and webhook receivers alongside a React/Next.js frontend
