```
export default class App extends Component {
render() {
// eslint-disable-next-line no-var
var settings = {
dots: true,
infinite: false,
speed: 500,
slidesToShow: 1,
slidesToScroll: 1,
initialSlide: 0,
arrows: true,
autoplay: true,
responsive: [
{
breakpoint: 1024,
settings: {
slidesToShow: 1,
slidesToScroll: 1,
infinite: true,
dots: true,
},

slidesToScroll: 1,
initialSlide: 2,
},
},
