html - 如何使用 react Hook 制作点状进度指示器组件？

Question

我想用 react-hooks 制作一个点状进度指示器。所以我有四个点表示进度。它从满到空，如果它是四个点，它是绿色的，三个黄色的，两个 - 红色的，一个是红色的。我想控制用 Prop 点亮的点的颜色和数量，并用 react-hooks 来完成。

我能找到的唯一接近它的是codepen上的“Dotted progress bar”，但它仍然与我想要的不同。

我希望输出是，如果我通过 0-25%，它只会点亮一个红色点，50-75% 黄色点亮等等。

我已经尝试了一段时间了，我尝试过的最远的是:

const OnGoingRequest = ({ image, name, profession, progress, color }) => {
  const [dotColor, setDotColor] = useState('#c4c4dd')
  if (progress > 0 && progress <= 25) {
    setDotColor('red')
  } else if (progress > 25) {
    setDotColor('blue')
  }
  return (
    <EachReview>
      <UserContainer>
        <UserImage src={image} />
        <UserInfoContainer>
          <UserName>{name} </UserName>
          <UserProffession>{profession} </UserProffession>
        </UserInfoContainer>
      </UserContainer>
      <ReviewStatusContainer>
        <Box>
          <Score />
          <Bar>
            <Progress progress={progress} color={dotColor} />
            <Dot />
            <Dot />
            <Dot />
            <Dot />
          </Bar>
        </Box>
        <ReviewStatusReachout>REACHOUT AGAIN</ReviewStatusReachout>
      </ReviewStatusContainer>
    </EachReview>
  )
}
export default OnGoingRequest

progress 作为 props 传递，我正在根据它进行检查，但我得到了太多重新渲染的错误。估计是返回前检查的缘故。

我找到了解决方案。我收到 1、2、3 或 4 作为 Prop ，我正在根据它进行渲染。

const OnGoingRequest = ({ image, name, profession, progress }) => {
  return (
    <EachReview>

          <UserProffession>{profession} </UserProffession>
        </UserInfoContainer>
      </UserContainer>
      <ReviewStatusContainer>
      {
        progress == 1 &&(
        <DotsContainer>
          <Dot color={'red'} />
        </DotsContainer>)
      }
      { progress === 2 && (
        <DotsContainer>
          <Dot color={'purple'} />
          <Dot color={'purple'} />
      </DotsContainer>
      )
      }
      {
        progress === 3 && (
          <DotsContainer>
            <Dot color={'yellow'} />
            <Dot color={'yellow'} />

      }
      {
