Yes, but asm.js is usually used as an intermediate language akin to Java 
bytecodes. cf Emscripten etc.

As I understand it, SpiderMonkey is for embedding Javascript in a 
(GUI-based) program, rather than for executing a Javascript or asm.js 
program from the command line (or from a makefile etc.) and getting text 

For example, this (via Google) 
shows a "Hello, World" in C++ being compiled using Emscripten, but the 
target is an HTML file rather than something that could be run from a 
shell or makefile.

[Later] Something like Rhino Shell might do the job. Possibly others.
