I’m wondering if its possible to write a javascript program and have it compiled and linked into an executable?
If so would it be possible to create a libjs that would be the equivalent of libc for the c/c++ world? wouldn’t creating something like this make javascript a full fledged language that could then be compiled and run directly on the target hardware?
If you had a compiler for javascript, couldn’t you write a new compiler in javascript?
Yes, you could write a js compiler. Not sure how popular it would be:
js engines are very fast these days, so you’re not gaining much speed.
It would be platform specific, or you would have to support multiple platforms. Not pleasant.
What would it be useful for? The great thing about an interpreted language is the very fact that it doesn’t need to be compiled. It shortens development cycles and build times (ever sat in front of a C program and had to change a file that the entire project relies on and had to run and rerun
makes that take minutes to compile everything?).Regarding your last point, you’re correct. Had you one of these compilers, you could indeed write another one in javascript.
