Getting the hostname from a URL

I found this helpful as a solution for formatting a URL (for example, to display it cleanly on a page).

const url = "https://developer.mozilla.org/en-US/docs/Web/API/URL"
const formatURL = (url) => {
  // Create URL object
  const urlObject = new URL(url);
  // Return hostname property value
  return urlObject.hostname;
}

console.log("Hostname:", formatURL(url)) // developer.mozilla.org
