Compared to other development platforms, Node.js has a specific workflow procedure. It operates on a single thread, meaning it does not create a new thread for every single request. A thread is basically a set of instructions that needs to be performed by the server.
The operation works like this, when there’s a request from the client to the web server, the single-threaded event loop picks it up and sends it to the worker thread present for processing.
This means it utilizes Non-blocking IO operations. Non-blocking I/O operations allow a single process to serve multiple requests at one time. Rather than wasting CPU resources and blocking the thread by waiting for a response, Node.js continues to work on the next task. So, in this manner, it can handle multiple concurrent tasks.
