javascript interpreter

js

There is a Javascript interpreter in the JavaScriptCore framework that comes with OS X. The interpreter is called jsc and can be found at the following path:

/System/Library/Frameworks/JavaScriptCore.framework/Resources/jsc

There is a built-in function, quit(), which will exit interactive mode.

If you want to make it easier to use I suggest creating a symlink to a location in your path, e.g.:

sudo ln -s /System/Library/Frameworks/JavaScriptCore.framework/Resources/jsc /usr/bin

This will put a symbolic link in /usr/bin
