How do I use the output of a node.js (or alike) program as a unix command line input?

Question

I have a simple node js program named test_cmd.js. I want to run this program through a unix shell, and use the output of the program to execute a unix command.

test_cmd.js can simply be:

console.log('echo "hello, world!"');

Output:

>> pi@raspberrypi ~/ $ node test_cmd.js >> echo "hello, world!" # I want the unix shell I just ran this program in to run this output as a command, but how?

You pipe it as stdin to the shell:

$ node test_cmd.js | bash hello, world!
