description npm Overview

npm is a command line tool and package manager primarily used by JavaScript developers. It facilitates the installation and management of software packages – often referred to as “nodes” – within the Node.js ecosystem. npm streamlines development workflows by automating dependency resolution and versioning, allowing projects to easily incorporate external libraries and tools into their codebases. This makes it essential for anyone building applications using JavaScript or Node.js.
