Node.js is Server-side scripting that is utilized to construct adaptable projects. Its various favorable circumstances over other server-side are dialects, the noticeable being non-blocking I/O. It is a JavaScript-based platform or runtime, which is built on Chrome's V8 JavaScript engine. It is a single-threaded program that employs the concurrency models that are based on the event loop. Instead of blocking the execution, it registers a callback which allows the applications to run. So, as per it, Node.js can handle all these concurrent operations without making multiple thread execution which can be scaled pretty well.
Along with JavaScript, it uses C and C++. These are used for interacting with the file system. Then, they are started using servers that are based on HTTP or TCP. Because of its rapidly growing popularity, it is now the most common platform for cross-platform or open platform apps. With the help of this, you can develop fast and scalable network apps that can be run smoothly on Linux, Microsoft Windows, or OSX.
