const parseUrl = (string, prop) =>  {
  const a = document.createElement('a'); 
  a.setAttribute('href', string);
  const {host, hostname, pathname, port, protocol, search, hash} = a;
  const origin = `${protocol}//${hostname}${port.length ? `:${port}`:''}`;
  return prop ? eval(prop) : {origin, host, hostname, pathname, port, protocol, search, hash}
}

// Examples
parseUrl('http://mysite:5050/pke45#23')
// {origin: "http://mysite:5050", host: "mysite:5050", hostname: "mysite", pathname: "/pke45", port: "5050"…}


parseUrl('http://mysite:5050/pke45#23', 'origin')
// "http://mysite:5050"
