Description
-----------

The JavaScript singleton is implemented only in HTML5 export. It's used to access the browser's JavaScript context. This allows interaction with embedding pages or calling third-party JavaScript APIs.

Member Function Description
---------------------------

.. _class_JavaScript_eval:

- :ref:`Variant<class_variant>` **eval** **(** :ref:`String<class_string>` code, :ref:`bool<class_bool>` use_global_execution_context=false **)**

Execute the string ``code`` as JavaScript code within the browser window. This is a call to the actual global JavaScript function ``eval()``.

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.
