You aren't using this any more? (Since you seem to be VLOGging it from C++
rather than console.logging it from JS.)

OK, then 1. Add a TODO explaining that this is for manual inspection and to be
removed later, and 2. Move this line down below var doodleData, and then just
write:

this.doodleData = doodleData;

Keeping it here for inspection purposes.

     var doodleData = data.ddljson;
     if (!doodleData || !doodleData.transparent_large_image) {
       setDoodleVisible(false);
