将键值对推送到多维数组中

function pushKeyValuePair(arr, keys, value) {
  if (keys.length === 0) {
    arr.push(value);
    return;
  }

  const key = keys.shift();
  if (!arr[key]) {
    arr[key] = [];
  }

  pushKeyValuePair(arr[key], keys, value);
}

// 示例用法
const multiDimensionalArray = {};

const keys = ['level1', 'level2', 'level3'];
const value = 'some value';

pushKeyValuePair(multiDimensionalArray, keys, value);

console.log(multiDimensionalArray);
