Is possible to execute js code in the shell?

[teone]

Hey,
I'd like to use this shell to create a tutorial on basic js command, is somehow possible to execute js code in the console?

Thanks

You can create a command that executes a JavaScript code string using eval().

Example:

shell.setCommandHandler("eval", {
    exec: function(cmd, args, callback) {
        callback(eval(args.join(" ")));
    }
});

// Shell
[1] $ eval "Hello, world!"
Hello, world!
