Node.js is a JavaScript runtime designed to build server-side applications. Node.js allows developers to build applications in one programming language instead of using a separate server-side one. This environment is event-driven, so Node.js sleeps if there is no work to be done. Finally, it is reasonable to develop scalable systems in Node.js, as its process never blocks.
Node.js is, in a way, an audit tool that checks if the JavaScript code is written correctly. Since you don’t need to use a browser for this, you speed up your JS writing process. Thanks to using Node.js, we create code according to best practice.
