Prototype Javascript Framework

$() function: for instance, you can write$('editForm').addClassName('active').show() to get the element with the ID ‘editForm‘, add a class name to it and show it (if it was previously hidden).
This framework can save you more than 50% on coding javascript and developing an ajax driven with large amount of DOM manipulations web site. If you have not tried it, please have a look. A well-defined framework is needed for developing a professional web application.
