How to get OS type in JS without callback wrapper

[ejaza7920015]

Hi, i want to get OS type without callback wrapper

let say in JS code if i do

getOStype(); // it should give either MAC or Windows

QUESTION: i want to avoid callback wrapper  

getOStype(function(ostype){
    //os type
});

Here is how i'm doing 

.jsx file

$._QEPPRO_={
     getOStype: function(){

         if (Folder.fs == 'Macintosh') {

            return 'MAC'

        } else {

            return 'WINDOWS';

        }

     }
};

var csInterface = new CSInterface();

csInterface.evalScript('$._QEPPRO_.getOStype()',function(osType){

      // osType
});

console.log(process.platform);
// returns "darwin" for mac
// returns "win32" for win
// I think you should have nodejs enabled in manifest.xml

var csInterface = new CSInterface(); //
console.log(csInterface.getOSInformation());
// mac example: "Mac OS X 10.14.6"
// win example: "Windows 10 64-bit"
