npm Package Manager

npm (Node Package Manager) is the default package manager for the Node.js JavaScript runtime environment and serves as the world's largest software registry. It is a command-line tool that allows developers to discover, share, and install reusable code packages, known as modules or dependencies, from the central npm Registry. By managing a project's dependencies in a manifest file called `package.json`, npm automates the process of installing, updating, and managing the libraries and tools a project needs to run, thereby streamlining the development workflow and ensuring consistency across different environments.
