jQuery and YUI (yahoo ui)

Question

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 1

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.
