Node is an open-source, cross-platform JavaScript run-time environment for developing server-side and networking applications. A peculiar feature of Node.js is its ability to process concurrent requests without delay. It uses an asynchronous programming method for doing so. Usually, when handling a request, the program sends this request to the computer’s file system. It then opens the requested file, reads it and then returns the content to the client.
