Show HN: Fast DOM manipulation with jQuery-like syntax

This is very cool, great work! Although I think you should make it clear in the read me that it only supports 2 basic jQuery-like selectors (by id '#id' and by class '.class'), ie: none of the following will work - 'div', '[name="test"]', '.class1.class2', '.class1 .class2', 'div.class .class2[data-test="thing"] > em#id:last-child' - I realise that last one should never be used in real life.

Some of these could be implemented with things like getElementsByTagName, getElementsByAttribute, and recursive calling when spaces are found. I may even do a pull request with these if I find time this weekend :)

Have you looked into using querySelectorAll? I'd be interested to know if it's slower and by how much.

That's only half the puzzle though, does this solution work in most browsers?

At least as many as jQuery 2.X?

Up to as many as jQuery 1.9.Y?

I looked at this the other day. While I think the effort is always good, a library like Sizzle already handles stuff like this and a lot, lot more. Its field tested and battle hardened. Its optimized for the 99% use cases, etc.

Nitpick: line 57 has a typo in 'undefined'. I will have a deeper look at the code tomorrow. A 30% increase is definitely interesting.

Would definitely like to use this -- could you please provide a license file?

problem is when u start adding features, u may again end-up with equal performances...Jquery community also takes care of performance but before that compatibility is first preference..

It looks cool! Adding a `remove` method would make it even better.

Cool. What's the use case?
