It also serves as a command-line utility for interacting with the npm online repository for package installation, version management, and dependency management. It is important to have Node.js installed in order to use npm. Also, working with updated versions of Node.js and npm ensures better performance and added features.Stable version of Node.js can be downloaded or updated from the official Node.js website as well as through the command line using Node Version Manager(nvm). nvm was originally developed for Linux systems, however nvm can be installed separately for Windows system by the following steps:
