Community Picks·2yNode.js is Single-Threaded But Still Concurrent. How?
Node.js is able to handle concurrent requests through its event-driven, non-blocking I/O model. This allows it to efficiently manage numerous connections simultaneously without the need for a dedicated thread per connection. The non-blocking I/O operations contribute to improved performance, making Node.js suitable for high I/O requirements. Additionally, the event-driven nature of Node.js simplifies code by eliminating the need for complex threading mechanisms.
