After brushing up on jQuery via a little light reading, I’ve started to play with the framework in code. I’m demoing a scrolling news ticker and decided to write it using jQuery and its Interface plug-in. Future iterations will probably include the history and easing plug-ins, too. In the meantime, though, it’s been two steps forward, one step back. I really dig the elegance of the jQuery API and its concise method-chaining. But there’s one integral element of the Prototype/Script.aculo.us framework that I miss: The Class object and the OOP training wheels it provides.
