2.3.0如何处理嵌套的json？

const jsonString = '{"name": "John", "age": 30, "address": {"street": "123 Main St", "city": "New York"}}';
const json = JSON.parse(jsonString);

import json

jsonString = '{"name": "John", "age": 30, "address": {"street": "123 Main St", "city": "New York"}}'
jsonDict = json.loads(jsonString)

// JavaScript
console.log(json.name);  // Output: John
console.log(json.age);  // Output: 30
console.log(json.address.street);  // Output: 123 Main St
console.log(json.address.city);  // Output: New York

# Python
print(jsonDict['name'])  # Output: John
print(jsonDict['age'])  # Output: 30
print(jsonDict['address']['street'])  # Output: 123 Main St
print(jsonDict['address']['city'])  # Output: New York

json.age = 35;
const newJsonString = JSON.stringify(json);
console.log(newJsonString);

jsonDict['age'] = 35
newJsonString = json.dumps(jsonDict)
print(newJsonString)
