preg: how to write a preg pattern to get domain name from an email?

Question

From an email address like something@gmail.com I want to fetch domain name gmail.com. i want to use that pattern on textbox value in Javascript.

Answer 1

A bit cleaner and up-to-date approach:

const email = "something@gmail.com"
const domain = email.includes('@') && email.split("@").pop()

Domain will be false if email doesn't contain @ symbol.
