No, multi-threading is not supported in Node.js. It is based on a single-threaded event loop model and uses asynchronous I/O to achieve concurrency. You can use the "worker" process to run child processes in separate threads, communicate with the main process through message passing, and delegate tasks to achieve multi-threaded concurrent programming.

Can nodejs be multi-threaded?

Does Node.js support multi-threading?

Answer: No, multi-threading is not supported in Node.js.

Detailed Description:

Node.js is based on a single-threaded event loop model, which means it can only perform one task at a time. It uses asynchronous I/O operations to avoid blocking and allows multiple tasks to run concurrently, but these tasks are executed sequentially in the same thread.

A common way to write multi-threaded code with Node.js is to use "worker" processes. Worker processes are child processes and can run in separate threads. By using the message passing mechanism, the master process can communicate with worker processes and delegate tasks to them.

Although there is no true multi-threading in Node.js, it provides a mechanism for concurrent programming through the event loop model and worker processes.
