如何从嵌套对象中获取唯一数组

function getUniqueArrayFromNestedObject(obj) {
  let tempArray = [];

  function traverseObject(obj) {
    for (let key in obj) {
      if (Array.isArray(obj[key])) {
        tempArray = tempArray.concat(obj[key]);
      } else if (typeof obj[key] === 'object' && obj[key] !== null) {
        traverseObject(obj[key]);
      }
    }
  }

  traverseObject(obj);

  // 去重操作
  let uniqueArray = Array.from(new Set(tempArray));

  return uniqueArray;
}

// 示例嵌套对象
const nestedObject = {
  a: [1, 2, 3],
  b: {
    c: [3, 4, 5],
    d: {
      e: [5, 6, 7]
    }
  },
  f: [7, 8, 9]
};

const uniqueArray = getUniqueArrayFromNestedObject(nestedObject);
console.log(uniqueArray);
