Javascript to Exe

Sometimes, I need to convert my javascript program to executable command-line. We spend a lot of time to implement an idea of a useful libraries, and sometime we want to use them in another different environment. Like today, I want to use my funtions in Javascript in command line. But I don't want to write again in different languages like perl, c or vb. I just want to convert.
