Mostly designed for building networking programs, the runtime is especially well suited for creating scalable network applications. Modules allow developers to implement various functionalities, thus reducing the complexity of the overall process and speeding up development.
One of the major advantages of Node.js is that functions are non-blocking. Multiple commands can be issued and run concurrently, which makes scaling up systems a lot more straightforward, as processes are never blocked. As a result, this framework is well-suited for applications that need to handle numerous concurrent connections without issues or slowdowns.
