Seems better with jQuery ajax call

I don't understand why we spend an entire unit learning jQuery then we go back to vanilla JS. It's kind of frustrating going back and forth on that. I redid the getJSON function with a jQuery AJAX call instead. 

function getJSON(url, callback) {
  $.ajax({
    type: "GET",
    url: url,
    dataType: "JSON",
    success: function (response) {
      return callback(response);
    }
  });
}

This to me seems much more succinct and it works perfectly. Why would we not always use jQuery for AJAX calls?

I think it's good to know how to do it in vanilla JaveScript, as doing it through jQuery AJAX might not always be an option.

I agree with you though, the jQuery way is much better and easier. I think that's jQuery in general though.

jQuery is essentially syntactic sugar. It's good to know what jQuery is actually doing behind the scenes and not having to load an entire library to run a simple XHR request is a bonus as well.
