Node.js does not wait for the server to respond to the request of the user terminal but it keeps on sending the requests without waiting for the results.
The C language further enhances the speed of node.js and increases its usability for many applications.
The speed with which it serves requests overshadows its limited ability to access multiple cores simultaneously. On the other hand, Java can access multiple cores, but it takes time to serve the requests and affect the real-time fast application of requests.
Other features that make Node.js more in demand include its flexibility in working with features like cluster module and balancing the load of various CPU cores. It facilitates the working of micro services by eliminating the wide modules.
It has features that make the framing of chat and gaming applications easy.
There is no doubt that Node.js is improvising with each day and is enhancing the standards of the codes and features. Open-source community is further facilitating the growth of technology. It is recording more than million downloads due to its ability to build real-time applications, Internet of Things and micro services.
