Question

I have a string would like everything after the last / to be returned.

E.g. for https://www.example.org/hackerbob, it should return "hackerbob".

Answer 1

I don’t think a regex is a good idea, seeing how simple the task is:

irb(main):001:0> s = 'https://www.facebook.com/hackerbob'
=> "https://www.facebook.com/hackerbob"
irb(main):002:0> s.split('/')[-1]
=> "hackerbob"

Of course you could also do it using regex, but it’s a lot less readable:

irb(main):003:0> s[/([^\/]+)$/]
=> "hackerbob"
