如何将嵌套数组转换为简单的typescript对象

function convertArrayToObject(arr: any[]): any {
  const obj: any = {};

  for (let i = 0; i < arr.length; i++) {
    if (Array.isArray(arr[i])) {
      obj[i] = convertArrayToObject(arr[i]);
    } else {
      obj[i] = arr[i];
    }
  }

  return obj;
}

const nestedArray = [1, 2, [3, 4, [5, 6]]];
const simpleObject = convertArrayToObject(nestedArray);
console.log(simpleObject);

{
  0: 1,
  1: 2,
  2: {
    0: 3,
    1: 4,
    2: {
      0: 5,
      1: 6
    }
  }
}
