Before you can start using NPM, you need to have Node.js installed on your computer. You can download the latest version of Node.js from the official website (https://nodejs.org/).
Once you have Node.js installed, you can start using NPM by opening a terminal or command prompt window. You can then use the following command to check if it is installed:

The first step in using NPM is to create a package.json file for your project. This file is used to manage your project’s dependencies, scripts, and metadata. You can create a package.json file by running the following command in your project’s directory:
npm init>
NPM makes it easy to install packages and add them to your project. You can install packages using the following command:
npm install
For example, to install the lodash package, you would run the following command:
npm install lodash>
The installed packages will be added to the dependencies section in your package.json file.
Once you have installed a package, you can use it in your project by requiring it in your code. For example, to use the lodash package, you would add the following code to your project:
var _ = require(“lodash”);
NPM makes it easy to keep your packages up-to-date. You can update all packages in your project by running the following command:
npm update>
Or, you can update a specific package by running the following command:
npm update
You can uninstall a package from your project by running the following command:
npm uninstall
