将对象的键和值转换为对象数组

function convertObjectToArray(obj) {
  const keys = Object.keys(obj);
  const result = [];

  for (let key of keys) {
    const value = obj[key];
    const newObj = { key, value };
    result.push(newObj);
  }

  return result;
}

// 示例用法
const obj = { name: 'John', age: 30, gender: 'male' };
const arr = convertObjectToArray(obj);

console.log(arr);
// 输出: [{ key: 'name', value: 'John' }, { key: 'age', value: 30 }, { key: 'gender', value: 'male' }]
