How do you set a dynamic date in Divi footer credits?

Place the following code in the Divi -> Theme Options -> Integration -> Head textarea.

<script>
 var beg_year = 2017; // Year site went live
 var this_year = new Date(); // Get current date
 var developed_by = ' | Powered by <a href="https://yourdomain.com" target="_blank">Your Development Company</a>'; // Developer info
 this_year = this_year.getFullYear();
 if(this_year > beg_year) {
 var year = beg_year + ' - ' + this_year;
 } else {
 var year = this_year;
 }
 var domain = window.location.hostname; //May be place in footer info below
 var company = 'Company Name';
 jQuery(function($){
 $('#footer-info').html('&copy; ' + year + '. ' + company + '.' + developed_by );
 });
</script>
