Hooks - End Function
--------------------

After all files are loaded, ``CssJsAsyncLoader`` looks for the javascript function ``CssJsAsyncLoaderFiles.endFunction`` and calls it if it exists. You might want to use this for hiding a loading screen, as soon as everything is loaded/rendered.

**Example**

.. code-block:: javascript

  CssJsAsyncLoaderFiles.endFunction = function() {
    document.getElementById('loadingScreen').classList.add = 'hidden';
  };

.. _hooks_minify_javascript:

Hooks - Minify Javascript
-------------------------

When the ``minify`` parameter is set for javascript resources, the function ``\TYPO3\CMS\Core\Utility\GeneralUtility::minifyJavaScript()`` is called. As can be seen in https://typo3.org/api/typo3cms/class_t_y_p_o3_1_1_c_m_s_1_1_core_1_1_utility_1_1_general_utility.html the function can be configured for javascript minification.
