How can I match the last part of an email via JavaScript?

I stumbled across (?<=\@)(.*?)(?=\.) here on StackOverflow, but apparently possitive lookbehinds are not supported in JavaScript.

I modified it a little to use /(@)(.*?)(?=\.)/ and I can obtain the last part of an email.

My problem is now trying to extract the last part if there are two . characters.

For example:

const[x, y, lastPart]="foo@bar.com".match(/(@)(.*?)(?=\.)/) //lastPart = bar 
const[x, y, lastPart]="foo@mailinator.com".match(/(@)(.*?)(?=\.)/) //lastPart = mailinator

These cases work perfectly, but when I try with foo@my.domain.com, I would like to extract my.domain and not my.

I am not interested in obtaining the `.com`, simply the bits between `@` and `.X` – Dan Apr 18 '18 at 10:38

Thanks for the answer. It may be duplicate but as someone who doesn't write regex, the answer in the post I "duplicated" doesn't express where I should put the code. – Dan Apr 18 '18 at 10:42
