I have an array filled with objects “fruits” which have properties “kind”, “color”. I need to use

quicksort 

method to sort given fruits by their colors in accordance to a given order of colors.
For example, an array “fruits” has

 {kind: apple, color: red}; {kind: orange, color: orange}; {kind: watermelon, color: green}; {kind: blueberry, color: blue}.

And you need to sort these fruits in accordance to rainbow color orders. How do we do that? All examples, that I have found on the internet only deal with numbers. I know that first step is to make a function which tells us the weight of a color in a given order:

const comparationColor = (fruit1, fruit2) => {
  const priority = ['violet', 'indigo', 'blue', 'green', 'yellow', 'orange', 'red'];
  const priority1 = priority.indexOf(fruit1.color);
  const priority2 = priority.indexOf(fruit2.color);
  return priority1 > priority2;
};  

And then there is a

quickSort 

function:

quickSort (arr) {
    if (arr.length < 2) {
        return arr;
    }
    
      let pivot = arr[0];
      let leftArr = [];
      let rightArr = [];
    
    for (let i = 1; i < arr.length; i++) {
          if (comparation(pivot, arr[i])) {
          leftArr.push(arr[i]);
        } else {
          rightArr.push(arr[i]);
        }
      }
      return [...quickSort(leftArr), pivot, ...quickSort(rightArr)];
      }

But how do I combine them?
