如何通过JavaScript更新JSON响应并返回修改后的JSON

var jsonResponse = '{"name": "John", "age": 30}';
var jsonObject = JSON.parse(jsonResponse);

jsonObject.name = "Alice";
jsonObject.age = 25;

var updatedJsonResponse = JSON.stringify(jsonObject);

function updateJsonResponse(jsonResponse) {
  var jsonObject = JSON.parse(jsonResponse);
  jsonObject.name = "Alice";
  jsonObject.age = 25;
  var updatedJsonResponse = JSON.stringify(jsonObject);
  return updatedJsonResponse;
}

var originalJsonResponse = '{"name": "John", "age": 30}';
var modifiedJsonResponse = updateJsonResponse(originalJsonResponse);
console.log(modifiedJsonResponse);
