This is my attempt at writing the shortest possible quine in JavaScript (targeting node.js). It's a mere 21 bytes. You can read more about the quine here. It only works in Unix-like systems (like Linux and Mac OS X).

Two helper scripts are included. init.sh will create the necessary directory and test.sh will run the quine. (You need to run init.sh as root by the way, and you only need to run it once.)

The quine itself is located in quine.js.

Suggestions and pull requests are welcome.

(There are also other types of JavaScript quines in the others directory just for fun.)
