Npm (Node Package Manager) is a package manager for Node.js. It is the default package manager for the JavaScript runtime environment Node.js. It consists of a command line client, also called npm, and an online database of public and paid-for private packages, called the npm registry.
Npm makes it easy for JavaScript developers to share and reuse code, and it makes it easy to update the code that you’re sharing.
Example:
Let’s say you have a project that needs to use a library called “lodash”. You can install it using npm by running the command:
npm install lodash
This will download the latest version of lodash and install it in your project. You can then require it in your code like this:
var _ = require(‘lodash’);
