对具有字符串键的数组中的对象进行排序

function quickSort(arr, key) {
  if (arr.length <= 1) {
    return arr;
  }

  const pivotIndex = Math.floor(arr.length / 2);
  const pivot = arr.splice(pivotIndex, 1)[0];
  const left = [];
  const right = [];

  for (let i = 0; i < arr.length; i++) {
    if (arr[i][key] < pivot[key]) {
      left.push(arr[i]);
    } else {
      right.push(arr[i]);
    }
  }

  return quickSort(left, key).concat([pivot], quickSort(right, key));
}

// 示例数据
const data = [
  { name: "John", age: 25 },
  { name: "Alice", age: 30 },
  { name: "Bob", age: 20 }
];

// 按照"name"键进行排序
const sortedData = quickSort(data, "name");
console.log(sortedData);

[
  { name: "Alice", age: 30 },
  { name: "Bob", age: 20 },
  { name: "John", age: 25 }
]
