How does Node.js work?

Q: How does Node.js work?

Short answer: Node.js operates on a single-threaded, event-driven architecture. Explain a bit more It uses the event loop to handle multiple connections concurrently, which means it can perform non-blocking I/O operations efficiently. 📌 Real-life analogy: Think of it like a chef (Node.js) who takes multiple orders (requests) but doesn't cook each dish one at a time. Instead, they prep and send off tasks (e.g., grilling, baking) and move on to the next customer while waiting. Say this in the interview Define — one clear sentence (the short answer above). Example — relate it to a project like ShopNest or your real work. Trade-off — when you would not use it.
