+If you're using Blueprint in Javascript, and don't have access to the Babel config (ie: using `create-react-app`), you won't be able to just use the decorator. You can, instead, use it as a [Higher-Order Component][react-hoc], and get to keep all the benefits of `ContextMenuTarget`:
+
+```jsx
+import { ContextMenuTarget, Menu, MenuItem } from "@blueprintjs/core";
+
+const RightClickMe = ContextMenuTarget(class RightClickMeWithContext extends React.Component {
+    render() {
+        // root element must support `onContextMenu`
+        return <div>{...}</div>;
+    }
+
+    renderContextMenu() {
+        // return a single element, or nothing to use default browser behavior
+        return (
+            <Menu>
+                <MenuItem onClick={this.handleSave} text="Save" />
+                <MenuItem onClick={this.handleDelete} text="Delete" />
+            </Menu>
+        );
+    }
+
+    onContextMenuClose() {
+        // Optional method called once the context menu is closed.
+    }
+});
+```
