I mean no offense to the author, but speaking of the DOM as if it is uniform in terms of performance seems silly. Pretty much every piece of API in the DOM has its own semantics and performance expectations (even if it's presented as a JavaScript property). Reading Element.offsetLeft, for instance, is a whole different world from reading Node.nodeType.

Just looking at their implementations in WebKit should tell you why:

Also, the code doesn't call into DOM directly but uses jQuery .html() for "reading" and .html(Math.random()) for "writing".

The case is extremely misrepresented indeed.

The DOM is a failed institution trying to grab on the the ledge before it falls into the abyss. W3C should be disbanded and HTML5 abandoned. JavaScript and it's ilk should be boycotted by users as well. This kind of complexity should exist on the server, not in the browser. I understand that people want to run complex apps in the browser. It's a bad idea in general but where it's needed, it should be PLATFORM DEPENDENT, implementing the tools that keep that platform safe. ie iOS, Windows, whatever. We are still in the browser wars, why are we so keen to adopt standards that aren't standard?

DOM Lvl 4 even features GC! Can we not see why this is a bad idea?!? Keyboard bindings also do not belong in a "standard". I wish this would get more attention by serious developers, but I think that most people who know better wouldn't care and aren't interested in understanding and digging into a lame standard. It's a land grab, only enterprises can and will ever be able to implement it correctly and completely, as the standard spreads to consume more of the user's space.

Here are some people who agree with me:

WTF is this? I don't even know where to begin with this crackpot of a post. You suggested nothing of value and just spout a bunch of FUD.

To your friends that agree with you from 2009, use `querySelectorAll` for a non-live NodeList, assuming he has kept up with JS actually having evolved and converging on standards.

I bet you flip your lid, too, to learn your server-side-only dystopia is running on top of JS (Node) services.

Can you please not be so abrasive on HN? Your points may be correct, but your tone is exactly what we're trying hard to avoid here.

Ah the white knight. Please please I beg you be nice.

I covered JS...

You have nowhere to begin because I'm absolutely right. The DOM is klausterfokken.

I'm trying to figure out if you're being sarcastic.

[AsymetricCom]

You have fun with that, and the DOM. I'm oute
