How NodeJS Handles Multiple Requests with a Single Thread

Introduction NodeJS has revolutionized server-side development by proving that a single-threaded runtime can handle thousands (or even tens of thousands) of concurrent requests efficiently. This often surprises developers coming from traditional multi-threaded environments like Java or PHP, where each request typically gets its own thread. But how does NodeJS achieve this without blocking or crashing under load? The secret lies in its event-driven, non-blocking I/O architecture , powered by the
