What appears to be missing is the automatic mapping of the A (ansi) and W (wide) suffixed function names to conventional unsuffixed function names. In C, this is done using macros. If UNICODE is not defined, the macro MessageBoxEx would expand to MessageBoxExA. With UNICODE, the macro expands to MessageBoxExW. Similarly, TEXT is used to wrap strings to ensure they're unprefixed or prefixed with an L respectively. You could do this by hand, it's just a bit more tedious to write.
One would wish these distinctions could be forgotten with calling the Win32api from JS. However, that is a pipe dream and could have an impact on performance.
You can forget the distinctions without impacting performance if your JavaScript engine uses UTF-16, because that's the native encoding of Windows NT 5.0+. You'll still get overhead when working with binary data, Typed Array or not.
This is fascinating, but I just can't discern a practical purpose.
The novelty of the "I just converted this huge piece of software written in c or machine code into JS" type of post usually extends only to the title. The link itself generally serves only to evoke a profound "WTF" (and in this case took upwards of 40 seconds to load.)
Although I appreciate the undertaking of compiling prodigious libraries, drivers, etc. into JS, I don't see practical value in the product of said undertaking.
The fact that this practice has proliferated throughout HN recently is odd. This kind of thing is certainly remarkable, but it doesn't do anything.
You're 100% right but you're missing something here. Something like this takes skill and builds skill and when you've finished you just want to show it off. And it really is impressive! Sure, it has no practical application itself but I'm sure that some piece of this or some technique used in porting it to JS will have some practical value somewhere. Sometimes the practical is born from the impractical.
I guess what I'm saying is why does it need to do anything or be practical? Cool stuff is just cool sometimes.
Windows script host (cscript) allows you to execute js files in addition to vbscript (vbs). This is particularly useful in extending the functionality of batch files. This can be useful in a lot of circumstances build process, installation etc.

Possibly with https://github.com/tjfontaine/node-libclang. I'm actually working on a node module that will automatically parse header files using libclang and make native dynamic libraries available with no configuration required on the end of the developer. It will eventually be part of https://github.com/olalonde/better-require if you're interested.
An didn't know about this, looks great. Would you be interested in helping me write an add-on for better-require? Anyways, I'll try it out and see how it works out.
The actual code generator I haven't published because it was kind of a pile of crap. I created bindings to libclang as well here but haven't finished rewriting a more generalized code generator from it https://github.com/Benvie/node-clang/blob/master/bindings.js
