如何将对象的每个属性都类型化为字符串？

function typecastObjectToString(obj) {
  for (let key in obj) {
    if (obj.hasOwnProperty(key)) {
      obj[key] = String(typeof obj[key]);
    }
  }
  return obj;
}

// 示例对象
const exampleObj = {
  name: "John",
  age: 30,
  isStudent: true,
};

// 类型化为字符串
const result = typecastObjectToString(exampleObj);
console.log(result);

{
  name: "string",
  age: "number",
  isStudent: "boolean"
}
