如何从推入平面数组的嵌套数组中获取值？

function getValueFromNestedArray(nestedArray, targetIndexArray) {
  if (targetIndexArray.length === 0) {
    return nestedArray;
  }

  const currentIndex = targetIndexArray.shift();
  const currentElement = nestedArray[currentIndex];

  if (Array.isArray(currentElement)) {
    return getValueFromNestedArray(currentElement, targetIndexArray);
  }

  return currentElement;
}

// 示例使用
const nestedArray = [1, [2, 3, [4, 5]], 6];
const targetIndexArray = [1, 2, 0];

const value = getValueFromNestedArray(nestedArray, targetIndexArray);
console.log(value); // 输出 4
