YUI3 vs jQuery
Everybody time to time comes to the dilemma which JS library to choose for further development. I used to work with prototype coupled with script.aculo.us and now use YUI3 in the office and jQuery at home. I like both of them, though finding each as the best one sui generis. YUI3 is a classical framework that provides design patterns and development philosophy as well as tool. jQuery is meant as a rapid, lightweight, flexible and pretty easy to start library. Its like Ruby on Rails and Python. Ruby and Python as languages are comparable (conceptual elegance against explicit consistency) and you will find APIs of both YUI3 and jQuery are quite similar.
