title: XMLHttpRequest is deprecated. What to use instead?
body: <p>Trying to use a pure JS approach to check if I have a valid JS image url. I am getting a warning that <code>XMLHttpRequest</code> is deprecated. What is a better way to do this?</p>
  
  <pre><code>urlExists(url) {
      const http = new XMLHttpRequest();
      http.open('HEAD', url, false);
      http.send();
      if (http.status !== 404) {
        return true;
      }
      return false;
    }
  </code></pre>
