Get Installed JavaScript Packages using npm

When working with JavaScript projects, it is common to use various packages or libraries to enhance functionality, improve efficiency, or solve specific problems. The npm is a package manager for JavaScript that allows managing dependencies and getting a list of installed JavaScript packages in the project. It provides an overview of all the dependencies used in a project, allowing developers to understand the project's ecosystem better. This knowledge helps in maintaining and updating packages, ensuring that the project remains secure and up-to-date with the latest features and bug fixes. This tutorial explains how to get installed JavaScript packages using npm.

The npm list command prints a list of all installed packages in the project. The command outputs information about each package, including the package name and version number. By knowing the installed packages, we can manage dependencies effectively, ensure version compatibility, and troubleshoot any conflicts that may arise.
