递归删除嵌套json对象中包含空数组的对象

function removeEmptyArrays(obj) {
  for (var prop in obj) {
    if (obj.hasOwnProperty(prop)) {
      if (Array.isArray(obj[prop]) && obj[prop].length === 0) {
        delete obj[prop];
      } else if (typeof obj[prop] === 'object') {
        removeEmptyArrays(obj[prop]);
      }
    }
  }
}

// 示例用法
var json = {
  "name": "John",
  "age": 30,
  "hobbies": [],
  "address": {
    "street": "123 Main St",
    "city": "New York",
    "phones": []
  }
};

removeEmptyArrays(json);
console.log(json);
