Getting Started with NPM
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/).

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 makes it easy to install packages and add them to your project. You can install packages using the following command:
npm install <package_name>
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.
Using Packages in Your Project
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:
Or, you can update a specific package by running the following command:
npm update <package_name>
You can uninstall a package from your project by running the following command:
npm uninstall <package_name>
