How to get artboard properties in photoshop CC 2015?

Also maybe this helps:

// 2015, use it at your own risk;
#target "photoshop-90.032"
if (app.documents.length > 0) {
var theArtboards = getArtboardStuff();
alert (theArtboards.join("\n"));
};
////////////////////////////////////
function getArtboardStuff () {
var originalRulerUnits = app.preferences.rulerUnits;
app.preferences.rulerUnits = Units.PIXELS;
// the file;
var myDocument = app.activeDocument;
// get number of layers;
var ref = new ActionReference();
ref.putEnumerated( charIDToTypeID("Dcmn"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") );
var applicationDesc = executeActionGet(ref);
var theNumber = applicationDesc.getInteger(stringIDToTypeID("numberOfLayers"));
// process the layers;
var theLayers = new Array;
for (var m = 0; m <= theNumber; m++) {
try {
var ref = new ActionReference();
ref.putIndex( charIDToTypeID( "Lyr " ), m);
var layerDesc = executeActionGet(ref);
// if artboard;
if (layerDesc.getBoolean(stringIDToTypeID("artboardEnabled")) == true) {
var artBoardRect = layerDesc.getObjectValue(stringIDToTypeID("artboard")).getObjectValue(stringIDToTypeID("artboardRect"));
var theName = layerDesc.getString(stringIDToTypeID('name'));
var theID = layerDesc.getInteger(stringIDToTypeID('layerID'));
theLayers.push([theName, theID, [artBoardRect.getUnitDoubleValue(stringIDToTypeID("left")), artBoardRect.getUnitDoubleValue(stringIDToTypeID("top")), artBoardRect.getUnitDoubleValue(stringIDToTypeID("right")), artBoardRect.getUnitDoubleValue(stringIDToTypeID("bottom"))]])
};
}
catch (e) {};
