 Method Descriptions
 -------------------
 
+.. _class_JavaScript_method_create_callback:
+
+- :ref:`JavaScriptObject<class_JavaScriptObject>` **create_callback** **(** :ref:`Object<class_Object>` object, :ref:`String<class_String>` method **)**
+
+Creates a reference to a script function that can be used as a callback by JavaScript. The reference must be kept until the callback happens, or it won't be called at all. See :ref:`JavaScriptObject<class_JavaScriptObject>` for usage.
+
+----
+
+.. _class_JavaScript_method_create_object:
+
+- :ref:`Variant<class_Variant>` **create_object** **(** :ref:`String<class_String>` object, ... **)** |vararg|
+
+Creates a new JavaScript object using the ``new`` constructor. The ``object`` must a valid property of the JavaScript ``window``. See :ref:`JavaScriptObject<class_JavaScriptObject>` for usage.
+
+----
+
+.. _class_JavaScript_method_download_buffer:
+
+- void **download_buffer** **(** :ref:`PoolByteArray<class_PoolByteArray>` buffer, :ref:`String<class_String>` name, :ref:`String<class_String>` mime="application/octet-stream" **)**
+
+Prompts the user to download a file containing the specified ``buffer``. The file will have the given ``name`` and ``mime`` type.
+
+**Note:** The browser may override the `MIME type <https://en.wikipedia.org/wiki/Media_type>`_ provided based on the file ``name``'s extension.
+
+**Note:** Browsers might block the download if :ref:`download_buffer<class_JavaScript_method_download_buffer>` is not being called from a user interaction (e.g. button click).
+
+**Note:** Browsers might ask the user for permission or block the download if multiple download requests are made in a quick succession.
+

+
 .. _class_JavaScript_method_eval:
 
 - :ref:`Variant<class_Variant>` **eval** **(** :ref:`String<class_String>` code, :ref:`bool<class_bool>` use_global_execution_context=false **)**
@@ -43,6 +81,14 @@ Execute the string ``code`` as JavaScript code within the browser window. This i
 
 If ``use_global_execution_context`` is ``true``, the code will be evaluated in the global execution context. Otherwise, it is evaluated in the execution context of a function within the engine's runtime environment.
 
+----
+
+.. _class_JavaScript_method_get_interface:
+
+- :ref:`JavaScriptObject<class_JavaScriptObject>` **get_interface** **(** :ref:`String<class_String>` interface **)**
+
+Returns an interface to a JavaScript object that can be used by scripts. The ``interface`` must be a valid property of the JavaScript ``window``. The callback must accept a single :ref:`Array<class_Array>` argument, which will contain the JavaScript ``arguments``. See :ref:`JavaScriptObject<class_JavaScriptObject>` for usage.
