But what exactly is a package manager, and why is it so important? A package manager is a tool for managing software packages. It automates the process of installing, upgrading, configuring, and removing software in a consistent manner. This makes it easy for developers to install and manage complex software systems without having to manually track and install dependencies.
Getting started with npm is simple. Just download and install Node.js from the official website (https://nodejs.org/en/), and then use the npm command-line interface (CLI) to install packages and manage your project’s dependencies. To install a package, use the npm install command followed by the name of the package you want to install. For example, to install the lodash package, you would run npm install lodash. This will download and install the lodash package and any dependencies it requires.
npm install lodash
const lodash = require('lodash');
// Use lodash in your code
const result = lodash.map([1, 2, 3], (i) => i * 2);
console.log(result); // [2, 4, 6]
