Final answer:
Yes, Node.js is generally considered single-threaded, but it has a non-blocking and event-driven architecture that allows for efficient handling of concurrent operations.
Step-by-step explanation:
Yes, Node.js is generally considered single-threaded, but it has a non-blocking and event-driven architecture that allows for efficient handling of concurrent operations.
Node.js runs on a single thread but uses an event loop to manage asynchronous operations. This means that while Node.js can handle multiple requests simultaneously, it does not create a new thread for each request like traditional multi-threaded servers.
Instead, Node.js uses callbacks or promises to handle asynchronous tasks, allowing it to perform other operations while waiting for I/O operations to complete. This non-blocking nature makes Node.js highly scalable and well-suited for handling real-time applications with heavy I/O operations.
