如何向嵌套的json添加属性？

let jsonObject = {
  "name": "John",
  "age": 30,
  "address": {
    "city": "New York",
    "zipcode": "10001"
  }
};

jsonObject.address.street = "Broadway";

{
  "name": "John",
  "age": 30,
  "address": {
    "city": "New York",
    "zipcode": "10001",
    "street": "Broadway"
  }
}

function addNestedProperty(obj, path, value) {
  let current = obj;
  let keys = path.split('.');
  
  for (let i = 0; i < keys.length - 1; i++) {
    if (!current[keys[i]]) {
      current[keys[i]] = {};
    }
    current = current[keys[i]];
  }
  
  current[keys[keys.length - 1]] = value;
}

// 使用示例
addNestedProperty(jsonObject, 'address.street', 'Broadway');
