使用javascript从嵌套对象中删除重复值

function removeDuplicates(obj) {
  const seen = new Set();

  function removeDuplicatesRecursive(obj) {
    for (let key in obj) {
      if (obj.hasOwnProperty(key)) {
        const value = obj[key];
        if (typeof value === 'object') {
          removeDuplicatesRecursive(value);
        } else if (Array.isArray(value)) {
          value.forEach(removeDuplicatesRecursive);
        } else {
          if (seen.has(value)) {
            delete obj[key];
          } else {
            seen.add(value);
          }
        }
      }
    }
  }

  removeDuplicatesRecursive(obj);
  return obj;
}

// 示例用法
const nestedObj = {
  a: 1,
  b: {
    c: 2,
    d: {
      e: 1,
      f: 3
    }
  },
  g: [1, 2, 3, 2],
  h: 'hello',
  i: {
    j: 'world',
    k: [1, 2, 3, 2]
  }
};

const result = removeDuplicates(nestedObj);
console.log(result);
