x86 assembler implemented in Javascript

This definitely falls under the category of, "Why? Because we can!" JSASM is an x86 assembler written completely in JavaScript. It's utterly useless, but therein lies the beauty. It's implemented in what is arguably the highest level language -- meaning far removed from the guts and gore of actual machine code -- in common use

Fewer budding young programmers work with assembly language these days, but way back in a decade we call the 1980s you just weren't a home PC hacker unless you could cobble together some simple ASM code to make your machine do stupid tricks. Go much further back than the 80s and, you'd need to have some assembly skills to get anything remotely interesting accomplished.

JSASM is open source (very!) so, if you ever wanted a deeper look inside an assembler, here's your chance.
