what is npm in node js

NPM stands for Node Package Manager, which is a package manager for Node.js packages or modules. It is a command-line utility that allows developers to install, update, and manage dependencies for their Node.js projects. NPM is installed on your computer when you install Node.js, and it is already ready to run on your computer. A package in Node.js contains all the files you need for a module, and modules are JavaScript libraries you can include in your project. NPM hosts thousands of free packages to download and use, and it creates a folder named "node_modules" where the package will be placed. All packages you install in the future will be placed in this folder. NPM can install all the dependencies of a project through the package.json file, and it can also update and uninstall packages.
