jQuery and YUI (yahoo ui)
So as i understand it jQuery is basically a framework for DOM manipulation as a higher abstraction layer then native javascript. Where as YUI (yahoo UI) library is a user interface widget library giving the developer a means to forget DOM manipulation and work more on business logic.
Is that right?
My Question: Is there any serious performance issues with including both libraries? and how does YUI compare to jQuery UI?
Answer
jQuery
$ DOM selection is powerful and works like magic.
jQuery code is usually very concise; helper functions exist for anything trivial (and non-trivial, even).
The plugin library is extensive and offers quick functionality.
jQuery is amazing for smaller sites and it’s easy to pick up for new users , which is why it has such a large community.
immediate results with less learning curve.
YUI
Great documentation and examples, as well as support from Yahoo with tech talks and frequent updates.
Code written with YUI tends to be organized. At times it even feels Java-esque. Has a rich set of modules for things other than DOM manipulation - cookies, cache, history, i18n, etc.
Particularly through Gallery, YUI has gotten more open to external contributions
YUI specialy YUI3 requires at least basic skill with the language, and more if you really want to exploit it well and extend it.
YUI is a lot more adapted for well organized, modular code which can be reused.
To see what YUI is capable of you can visit here for examples of YUI2 , and here for YUI3 galleries(which are IMO a bit similar to JQuery plugins ) .
You can refer this site to compare YUI and jquery's speed .
IMO JQuery is a library , YUI is a framework and not a library. JQuery is good for small websites where you want to achieve a ‘WOW’ factor in relative short time. But when you are building an application, you need a robust framework where you can integrate your own codes yui is better choice.
