Node.js & Libuv•Part 5: Production Scale, Deployment & Observability (51 - 60)
Node.js Event-Driven I/O vs Multi-Threaded Runtimes (Java/Go).
In Simple Words: Node.js uses a single event loop thread with non-blocking I/O, consuming ~30MB RAM for 10,000 idle connections. Java traditionally allocates 1MB stack per thread, consuming gigabytes of RAM. Go uses lightweight user-space goroutines (~2KB stack) for multi-threaded concurrency.

// 10,000 idle TCP connections consume minimal RAM in Node.js:
const net = require('net');
const server = net.createServer((socket) => {
socket.write('Connected to lightweight event-driven server');
}).listen(9000);
