关于setState不能及时获取最新值

[liuhailang]

这里的currentSlide !== this.state.currentSlide永远不会成立
const { currentSlide } = this.state;

this.setState({
  currentSlide: Math.min(Math.max(index, 0), this.len - 1),
});

// eslint-disable-next-line react/destructuring-assignment
if (currentSlide !== this.state.currentSlide) {
  this.slideToCurrent();
  onChange.call(this);
  if (callback) {
    callback.call(this);
  }
}

Carousel 组件已经用 hooks 重构了，你说的问题已不存在
