+# Render An Array Of Elements With React 16
+
+React 16 was released today. Among many exciting features and updates is
+support for rendering an array of elements.
+
+This can look as simple as this example:
+
+```javascript
+return [
+  <li key="1">One</li>,
+  <li key="2">Two</li>,
+  <li key="3">Three</li>
+];
+```
+
+It really shines in the case of generating elements from an array of data.
+
+```javascript
+let data = [
+  { value: "One", key: "1" },
+  { value: "Two", key: "2" },
+  { value: "Three", key: "3" }
+];
+return data.map(item => {
+  return (
+    <li key={item.key}>
+      {item.value}
+    </li>
+  );
+});
+```
+
+No need to wrap the result in a `<div>`!
