Npm is a package manager for the JavaScript programming language. It is the default package manager for the Node.js runtime environment and can be used to install, uninstall, and publish new packages. Also, npm is not an installer. It is most commonly used in combination with Node.js, the JavaScript platform built and maintained by Joyent and best known as the runtime for npm itself. You use npm to install Node.js, and any version of Node.js, you can use npm to look up, download, and publish packages containing any kind of code you want: command line tools, GUI tools, webservices over HTTP or TCP or WebSockets, anything you might want to publish for consumption by other people in the JavaScript community.
