Create four sliders in React with a sum constraint of 100

To create four sliders in React with a sum constraint of 100, you can follow these steps:

1- Create a state object that will hold the values of the four sliders.

const [sliderValues, setSliderValues] = useState({
  slider1: 25,
  slider2: 25,
  slider3: 25,
  slider4: 25,
});

2- Create a function that will handle changes to the sliders. This function will take the name of the slider that was changed and its new value. It will then update the state object with the new value and adjust the values of the other sliders so that the sum of all four sliders is always 100.

const handleSliderChange = (sliderName, newValue) => {
  // Calculate the sum of the other three sliders
  const otherSliderValuesSum =
    sliderValues.slider1 +
    sliderValues.slider2 +
    sliderValues.slider3 +
    sliderValues.slider4 -
    sliderValues[sliderName];

  // Calculate the new value for the current slider
  const newSliderValue = Math.min(100 - otherSliderValuesSum, newValue);

  // Update the state object with the new slider value
  setSliderValues({
    ...sliderValues,
    [sliderName]: newSliderValue,
  });
};

3- Render the four sliders and pass the name and value of each slider to the handleSliderChange function.

return (
  <div>
    <Slider
      value={sliderValues.slider1}
      onChange={(event, value) => handleSliderChange('slider1', value)}
    />
    <Slider
      value={sliderValues.slider2}
      onChange={(event, value) => handleSliderChange('slider2', value)}
    />
    <Slider
      value={sliderValues.slider3}
      onChange={(event, value) => handleSliderChange('slider3', value)}
    />
    <Slider
      value={sliderValues.slider4}
      onChange={(event, value) => handleSliderChange('slider4', value)}
    />
  </div>
);

This will create four sliders with a sum constraint of 100, where changing the value of one slider will automatically adjust the values of the other sliders so that the sum is always 100.
