从两个不同的多维数组中获取唯一值

function flattenArray(arr) {
  return arr.reduce((flat, toFlatten) => {
    return flat.concat(Array.isArray(toFlatten) ? flattenArray(toFlatten) : toFlatten);
  }, []);
}

function getUniqueValues(arr1, arr2) {
  const flattenedArr1 = flattenArray(arr1);
  const flattenedArr2 = flattenArray(arr2);

  const combinedSet = new Set([...flattenedArr1, ...flattenedArr2]);
  return Array.from(combinedSet);
}

// 示例
const array1 = [[1, 2], [3, 4]];
const array2 = [[3, 4], [5, 6]];

console.log(getUniqueValues(array1, array2)); // 输出: [1, 2, 3, 4, 5, 6]

function flattenArrayIterative(arr) {
  const stack = [...arr];
  const result = [];
  while (stack.length) {
    const next = stack.pop();
    if (Array.isArray(next)) {
      stack.push(...next);
    } else {
      result.push(next);
    }
  }
  return result.reverse();
}
