 The ``ngettext`` function provides an interface to pluralize words and

 * Named interpolation: This mode is selected by passing the optional
   boolean ``named`` parameter as ``true``. ``obj`` contains a JavaScript
   object or associative array. For example::
 
-    d = {
-        count: 10,
-        total: 50
+    const data = {
+      count: 10,
+      total: 50

 You shouldn't go over the top with string interpolation, though: this is still
 JavaScript, so the code has to make repeated regular-expression substitutions.
