+// Exercise:
+//
+// - render DATA.title in an <h1>
+// - render a <ul> with each of DATA.items as an <li> and display the name
+// - limit the list to only mexican food (hint: use DATA.items.filter(...))
+// - sort the items in alphabetical order by name
+//   (hint: use sort-by https://github.com/staygrimm/sort-by#example)
+//
+// Got extra time and know some React already?
+// - add a select dropdown to make filtering on `type` dynamic
+// - add a button to toggle the sort order
+// - Hint: you'll need an `updateThePage` function that calls `render`,
+//   and then you'll need to call it in the event handlers of the form controls
