js 怎么删除json对象

let jsonObject = {
  "name": "John",
  "age": 30,
  "city": "New York"
};

delete jsonObject.age;

console.log(jsonObject); // 输出: { name: 'John', city: 'New York' }

let jsonObject = {
  "name": "John",
  "age": 30,
  "city": "New York"
};

// 使用 Object.assign
jsonObject = Object.assign({}, jsonObject, { age: undefined });

// 或者使用扩展运算符
jsonObject = { ...jsonObject, age: undefined };

console.log(jsonObject); // 输出: { name: 'John', city: 'New York' }

let jsonObject = {
  "name": "John",
  "age": 30,
  "city": "New York"
};

jsonObject = JSON.parse(JSON.stringify(jsonObject, (key, value) => {
  if (key !== 'age') return value;
}));

console.log(jsonObject); // 输出: { name: 'John', city: 'New York' }
