Step 3 – Add JavaScript
We use some external JavaScript link to this code. No need to worry about this, copy and paste below code between <head></head> tag.
<head>
<script src="//cdnjs.cloudflare.com/ajax/libs/moment.js/2.5.1/moment.min.js"></script>
</head>
And also copy and paste below JavaScript code between <script></script> tag.
