SPFx how to identify type of list's view?

public async getView(): Promise<IViews[]> {
          let viewsList: IViews[] = [];
          const itemsViews = await sp.web.lists.getByTitle("Avtal Demo").views.get();
          itemsViews.forEach(item => {
                  viewsList.push({
                           Title: item.Title,
                           Id: item.Id
                  });
          });

          console.log(itemsViews);

          return new Promise<IViews[]>(async resolve => {
                resolve(viewsList);
          });
}

The console log print out all information about the view. 

What I need to do is find the way to differentiate  a view that is a grouped view from one that is filtered view.

Is that possible?
