In the JavaScript framework used by Safari and other parts of Apple’s products, there is a tool called
jsc. It’s a command line interface for JavaScript that uses the same code as the rest of the system.You can find the binary at
/System/Library/Frameworks/JavaScriptCore.framework/Versions/Current/Helpers/jsc. That path is unwieldy, so I have an alias set up that lets my just typejscin the Terminal.So what can you do with
jsc? Pretty much anything you can do with JavaScript in a browser with the caveat that there aren’tdocumentandwindowinstances.
