  * ## In addtion to the above, Angular privides an additional method to both jQuery and jQuery lite:
  *
  * - `scope()` - retrieves the current Angular scope of the element.
+ * - `injector()` - retrieves the Angular injector associated with application that the element is
+ *   part of.
  * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
  *   parent element is reached.
