The main purpose of Moment.js is to get the current time in different formats to use them in other ways. The main reason I use it is to get the current time while making any changes in the database, so that I can change the "LastModifiedOn" property in the database and create a new row and provide a value for the "DateCreatedOn" field in the database. 

Let's get to using Moment.js in a Node.js application.

Step 1

Install moment package in the application from npm, using the following command:
npm install moment --save

This will install Moment.js in the application as well as save the js for the same.

Step 2

Now, include this Javascript in your app.js, using the code below:

var moment = require('moment');  


Step 3

The next step is to call this moment variable to get different format values. Some examples are shown here:
