But this does not utilize efficiently multiple cores of a CPU. As most of the servers are limited by the number of threads or resources. Single-threaded model for Node Js:Īs node js does not have threads, this makes the server handle a very high volume of incoming requests. There may be multiple threads for handling requests, but again threads are limited by resources. If a request is synchronous, the server has to complete that request first then go to process the next request.

Each API call can specify the callback function when the API completes the callback function is called. This is achieved in Node js with the concept of call-back functions.
