To Extract src of <img> element (selected by class) from multiple HTML pages in node.js use the following steps:-

1. Download each page in a loop with AJAX.
2. Parse the DOM with something like jsdom.
3. Use a selector with [querySelectorAll()].(https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelectorAll) to get each image element.
4. Use a regular expression on the image src-attribute to get the robot name. Like: $img.src.match(/([^\/]+).png$/i)[1].
5. Download all the robots with AJAX.
6. Combine robot name and downloaded robot to an object with key value pairs.
