Fourth Question

Write out the request and response cycle. What is its purpose? How does it work?

Fifth Question

Check out the JSON you get from making a GET request to this url (https://randomuser.me/api/). Open up the Github repositiory for this reading and view the provided src/index.html file in the browser. In src/index.js, make an AJAX request to that url when the button is clicked and append the retrieved information to the DOM. Use the labels to append the right data in the appropriate h4's, h3's and img tags.
