Unable to get object handle from GLTFLoader

@Mugen87 Appreciate your response!
I followed your suggestion of working with promises and could make things work using following:

const _THREEJSHELPER = {
  asyncModelLoader: (url) => {
    let loader = new GLTFLoader();

    return new Promise((resolve, reject) => {
      loader.load(url, data => resolve(data), null, reject);
    })
  }
}

Used it like this:

(async () => {
  let tempObject = await _THREEJSHELPER.asyncModelLoader('models/object.glb');
  obj2 = tempObject.scene;
  scene.add(obj2);
})();
