Question

www.mydomain.com/invite/abc123

I want the function to return “abc123”. The logic goes like this:

If there is a forward slash, then take all characters after the last forward slash.

In python, I write it like this:

if s.find('/') >= 0:
    return s[s.rfind('/')+1:]

But how do I do this in javascript?

You don’t need regexp to do this.

var s = "www.mydomain.com/invite/abc123";

if(s.indexOf("/")>=0)
    alert(s.split("/").pop());
