NPM (Node Package Manager) is the default package manager for the Node.js runtime environment. It is a tool that allows developers to easily install, manage, and share JavaScript libraries and packages with other developers. NPM is widely used in the JavaScript community for managing dependencies in web development projects, as well as for building and deploying server-side applications using Node.js.
NPM provides a command-line interface (CLI) for developers to interact with the NPM registry, which is a repository containing thousands of open-source packages published by the community. With NPM, developers can:
Install packages and dependencies for their projects.
Update or remove packages as needed.
Publish and share their own packages with other developers.
Manage versioning and resolve dependency conflicts.
To use NPM, you need to have Node.js installed on your system, as NPM comes bundled with it. Once installed, you can use the npm command in your terminal or command prompt to interact with the NPM registry, manage your project's dependencies, and run scripts defined in the package.json file of your project.
