How to write device drivers in Javascript?

Question

Is it possible to write hardware drivers in Javascript? What would be the steps required for such a task?

Also, I was unsure where to post this, so any suggestions regarding this are also welcome. I hope this is the accurate location for the question.

Answer 1

No. Not really. I mean, you sort of could by writing something that compiles Javascript into C, but that would be pretty crazy. Bit like trying to use a spoon as a chainsaw.

Learn C. That is the right tool for the job.

Answer 2

Oh, gosh. Writing a driver in js? Why? I mean, you could write a javascript wrapper for something in C or C++, maybe, but why would you want to do that? Device drivers communicate with the machine at a fairly low level (hardware level). Javascript doesn't. Javascript is a web language (well, mostly).

As Rich Bradshaw said, it's like using a spoon as a chainsaw. Though to me it'd be more like trying to use a canoe as a tank.

Wow, this idea is non-sense, IMHO you pick a programming language to solve a problem or task and not the other way around. I work with device drivers and OS kernel related stuff, but just because I can program in C I don't use C to do other task such as Linux administration for my embedded device; instead, I use something high level such as Bash, Perl or Python (depending on my mood :)).

Why are you interested in js? Actually, you should understand the internals of the programming language to know what are you trying to achieve and also you need to know how you program will interact with you OS to communicate with device registers and interrupts among other things.
