javascript event is from jquery code example
Example: jquery event listener
// There are quite a few abstracted versions of the following
$('element').on('event', function() {
// Do something
});
// Where 'event' is something such as 'click', 'hover' etc
// They are abstracted as seen below
$('element').click(function(){
// Do something
});
$('element').hover(function(){
// Do something
});
// etc...
