如何为数组中嵌套数组中的多个对象生成连续索引

function generateIndexes(arr) {
  let index = 0;

  for (let i = 0; i < arr.length; i++) {
    const nestedArray = arr[i];

    for (let j = 0; j < nestedArray.length; j++) {
      const obj = nestedArray[j];
      obj.index = index++;
    }
  }

  return arr;
}

// 示例用法
const array = [
  [{ name: 'obj1' }, { name: 'obj2' }],
  [{ name: 'obj3' }, { name: 'obj4' }],
  [{ name: 'obj5' }, { name: 'obj6' }]
];

const result = generateIndexes(array);
console.log(result);
