There was a [great article][1] about how react implements it's virtual DOM. There are some really interesting ideas in there but they are deeply buried in the implementation of the React framework.
However, it's possible to implement just the virtual DOM and diff algorithm on it's own as a set of independent modules.

To run this, you can try:
curl -ksO https://gist.githubusercontent.com/nicerobot/2697848/raw/uninstall-node.sh
chmod +x ./uninstall-node.sh
./uninstall-node.sh
rm uninstall-node.sh

| 1) Install VirtuaBox on your mac | |
| http://download.virtualbox.org/virtualbox/4.1.10/VirtualBox-4.1.10-76795-OSX.dmg | |
| 2) Decide which versions of Internet Explorer you want to download and install – each version of Internet Explorer is contained within a separate virtual machine that runs within VirtualBox. In other words, if you want to run Internet Explorer 7, 8, and 9, you will need to download three separate VM’s, which may take a while so keep that in mind. Select the text below and copy it: | |
| # Install ALL versions of Internet Explorer: IE 7, IE 8, and IE 9 (for now this script will also pull down a IE 6 vm with windows xp) |
