如果json数据有转义字符，该如何解析？

var jsonString = '{"name":"John","age":30,"city":"New York"}';
var jsonObject = JSON.parse(jsonString);

console.log(jsonObject.name); // Output: John
console.log(jsonObject.age); // Output: 30
console.log(jsonObject.city); // Output: New York

import json

jsonString = '{"name":"John","age":30,"city":"New York"}'
jsonObject = json.loads(jsonString)

print(jsonObject['name']) # Output: John
print(jsonObject['age']) # Output: 30
print(jsonObject['city']) # Output: New York
