[jQuery] slick.js의 응답 옵션 오류?

조건

<div class="slider responsive">
  <div><h3>1</h3></div>
  <div><h3>2</h3></div>
  <div><h3>3</h3></div>
  <div><h3>4</h3></div>
  <div><h3>5</h3></div>
  <div><h3>6</h3></div>
  <div><h3>7</h3></div>
  <div><h3>8</h3></div>
</div>

$('.responsive').slick({
  dots: true,
  infinite: false,
  speed: 500,
  slidesToShow: 5,
  slidesToScroll: 1,
  responsive: [{
    breakpoint: 768,
    settings: {
      slidesToShow: 2,
      slidesToScroll: 2,
      dots: true
    }
  }]
});

무슨 일이 일어날까요?

무엇 때문에?
