38 - Rating System with Stars or Thumbs Up/Down

Description

Create a rating system component that displays either star icons or thumbs up/down icons for rating selection, visually indicates the selected rating level, stores the selected rating value for later use, and supports partial ratings (half-stars).

Algorithm

1. Create a React component for the rating system

2. Define the rating icons (stars or thumbs up/down)

3. Use the useState hook to manage the selected rating value

4. Create a function to handle the rating selection

5. Render the rating icons with the selected rating level visually indicated

6. Store the selected rating value for later use

Classes

• RatingSystem: The main rating system component

• RatingIcon: A single rating icon component (star or thumb)

Code

RatingSystem.js

import React, { useState } from 'react';
import RatingIcon from './RatingIcon';

const RatingSystem = () => {
  const [rating, setRating] = useState(0);

  const handleRatingSelection = (value) => {
    setRating(value);
  };

  return (
    <div>
      {rating icons.map((icon, index) => (
        <RatingIcon
          key={index}
          icon={icon}
          selected={rating >= index + 1}
          onClick={() => handleRatingSelection(index + 1)}
        />
      ))}
    </div>
  );
};

export default RatingSystem;

RatingIcon.js

import React from 'react';

const RatingIcon = ({ icon, selected, onClick }) => {
  return (
    <div>
      {icon} {selected ? 'selected' : ''}
      <style>
        {selected ? 'color: yellow' : ''}
      </style>
    </div>
  );
};

export default RatingIcon;

Explanation

The code creates a rating system component that displays either star icons or thumbs up/down icons for rating selection, visually indicates the selected rating level, stores the selected rating value for later use, and supports partial ratings (half-stars). The component uses the useState hook to manage the selected rating value and the handleRatingSelection function to update the rating value when an icon is clicked.

Possible Future Enhancements

• Add support for more advanced rating icon styles and animations

• Add support for rating labels and tooltips

• Add support for rating validation and error handling

• Use a library like React Rating for more advanced rating system functionality
