This simple plugin changes the $() function behavior to the one that jQuery users got used to
First of all it changes a bit the way you navigate through the pages
$('#element-id'); // -> Element
$('div.css#rule'); // -> Array of Elements
Unlike jQuery, RightJS differs access to a separated element and a group of elements, but general feeling is about the same.
The second thing that this plugin does, it allows to call a certain function when the document is loaded in the way they do it in jQuery
$(function() {
// same as $(document).onReady
});
This is about it, simple and useful.
