Exactly! I used to just use a document.getElementById wrapper until I discovered Binny V A’s getElementsBySelector (improved version of Simon Willison’s) – until I realized I needed more powerful CSS3 selection. Then I found Peppy. It’s great!

Greate. Billions of years ago I used to use my own css selector. Then, I replaced it by the css selector of some Simon Willison (Does anybody know him?). His selector is the fastest i ever saw, but with limitations and some bugs.

Now, the time has come to start using Peppy. Thanks James

There were more fast and right libraries from Peppy and Sizzle.
* uupaa-selector (IE 6+, Fx2+)

* ksk (IE 5+, Fx1+)

@Jim Neath: Peppy has not copied parts from sizzle, nor has it copied parts from any other source. It was written by me from the ground up. I worked very hard on Peppy and to propagate the message that I have copied code is not fair and is not justified. If you actually take a look at the source code you can see that it is dramatically different from Sizzle or any other library out there.

@Shaun: Peppy does use caching (as does Sizzle), however in browsers that do not support DOM mutation events this is turned off. Browsers that do support DOM mutation events caching is cleared as soon as the DOM changes so this is not an issue.

Thanks for this information, I will go for Sizzle.

Also, parts of Peppy have been copied straight from Sizzle.

I’d just use Sizzle.

Be careful using Peppy. It works by storing the page in a variable first. If you make any changes to your page on the fly with JavaScript, Peppy won’t see them.

I recommend Sizzle by John Resig. (http://github.com/jeresig/sizzle/tree/master).

It’s very much faster than Prototype which I am using in all systems, so I should incorporate this one for sure! On the benchmark though, on my Vista box ExtJS is by far the fastest one – however this is the commercial one so I would expect it being best.

However 6x prototype is a real enhancement overall!

Nice tip, will download!
