JS: How to get the site name?

Question

Example urls:

let str = 'https://www.google.com.ua/images/branding/product/ico/googleg_lodp.ico'
let str1 = 'https://www.google.com/images/branding/product/ico/googleg_lodp.ico'
let str2 = 'https://books.google.com.ua/images/branding/product/ico/googleg_lodp.ico'

How can I get only the site name from such urls? Only the word - google.

what do you mean by site name? lets say for str2 what are you expecting? — samnu pel, Aug 25 '17 at 19:50
Sarath Kumar, this answer is not suitable. There does not account for the subdomain and second level domain. — VINET, Aug 25 '17 at 19:57
Koushik Chatterjee, str - google, str1 - google, str2 - google — VINET, Aug 25 '17 at 20:02

The following pattern will return the group name with what you want:

[.+:\/\/]?[^.]*\.?(?<name>[^.]+).+

It will work in cases of urls like https://google.com.br, for example.Let me know if you think this way is sufficient.

EDIT:

It is very difficult to treat cases like I pointed:

In the first case, the correct return would be google, but in the second case the desirable result is books.

this does not detract from the subdomain, if I understand correctly. Can make of this js function? – VINET Aug 25 '17 at 20:16

This works reasonably well:

https?.*?(\w{4,})(?=(?:\.\w{2,3})+\/)

The name is in group 1.

Demo. It's likely better to use a whitelist of TLDs.
