Gameboy emulator in Javascript

[ZiNgA BuRgA]

For anyone interested, someone decided to use Javascript to write a guide about writing a Gameboy emulator:

Obviously, not really usable, but probably might provide someone with something interesting to look at.

I've only scanned over the first page very quickly, but it does appear to give a quick introduction on the basics of the CPU, for those not familiar with low level environments (and I assume it would do the same for other topics).
