      type: Function,
      default: null,
      changed(newValue: Function) {
        console.log(12312313);
        console.log(newValue);

        if (this instanceof YSwitch) {
          this.update();
        }
      }
    }
  };
  render(props: any) {
    console.log(props);
    return <div>hallo,omi</div>;
  }
}
