=========================
AddJavaScriptModulesEvent
=========================

JavaScript events in custom user settings configuration options should not be
placed as inline JavaScript. Instead, use a dedicated JavaScript module to
handle custom events.


Example
=======

..  todo: \TYPO3\CMS\Setup\Event\AddJavaScriptModulesEvent->addModule and
    \TYPO3\CMS\Setup\Event\AddJavaScriptModulesEvent->getModules was removed
    with TYPO3 v13.0, please update the example.
