Writing an x86 emulator in JavaScript

Here’s another one:

I know you're not too interested in performance here, but replacing DataView with a Uint8Array will probably get you a 10x+ win - DataView is extremely slow and V8 can't optimize calls to Program.getUint8(PC) in the same way that it can optimize Program[PC].

Thanks, indeed I didn't make any efforts to make it faster, but this seems fair... I honestly didn't know DataView was that slow, it got fibonacci(40) down to 1m53s. Faster than PERL according to http://fengmk2.com/blog/2011/fibonacci/nodejs-python-php-rub...

Writing an x86 emulator to run in javascript on an x86 machine. (although of course this would work on ARM etc. too).

Pretty cool though in all fairness.
