I’ll introduce JavaScript code that extracts only the domain part after @ from an email address.

Code to Extract Only the Domain Part After @ from Email Address

Using the String.prototype.split() method, you can extract only the domain part after @ from an email address with the following code:

var emailAddress = 'sample@exaple.com';
var emailDomain = emailAddress.split('@')[1];

console.log(emailDomain);
// 'exaple.com'

You could also extract it using regular expressions, but this time I wrote code using the split method, prioritizing clarity.
