Is there a way to get top level domain name from the url
for e.g., \"https://images.google.com/blah\" => \"google\"
I found this:
var domain = n
You could do this:
location.hostname.split('.').pop()
EDIT
Saw the change to your question, you would need a list of all TLDs to match against and remove from the hostname, then you could use split('.').pop()
// small example list
var re = new RegExp('\.+(co.uk|me|com|us)')
var secondLevelDomain = 'https://www.google.co.uk'.replace(re, '').split('.').pop()
